yes 
The presence of a BM program for a musician not doing a BM can mean fewer opportunities at some schools. But Rayrick you know that and have probably checked it out
I think study abroad might be hard doing those two majors, not sure. So many required courses in sequence for two different areas of study.
Good to see the link on the sun lamp. Stay away from Finland!!
"Essentially, I’m looking for a school with similar academic flexibility and opportunity to Rochester, but ideally situated somewhere warmer or more lively. Any suggestions would be appreciated; I honestly don’t even fully know where or how to start looking. "
Then you need to check out University of Southern California.
It has all that you need and want- the flexibility to double major in 2 totally diverse areas, a great music school- [Thorton ], a great CS program in the Engineering Program[ Vertibi] , sunny warm weather, happy students , lots of openings for transfer students, FA for transfer students, and the advantage of being at a U that has the top Cinematic Arts program in the country.
I really can’t believe that no one had suggested USC. 
Tulane’s CS department is small with limited offerings, unless the student wants to focus on theory.
Re: CS at various smaller schools
Here is a comparison of some of the CS course offerings at various smaller schools:

Some people on these forums seem to think that they are the only companies hiring CS majors, and/or that the presence of them recruiting at a college makes the college somewhat special. In reality, they are big enough to have both the resource and needs to recruit widely, so their presence on campus is not that special (and students know who they are and can apply to them directly). It is the many smaller companies that are less well known, and whose recruiting on campus may alert students to their existence. Many of the smaller companies do little travel recruiting, though they are more likely to recruit at more local or regional schools where travel is less of a hassle.
@compmom, rest assured we’ve been focusing exclusively on schools where non-B.M. seekers have full access to all of the musical offerings at the school. That’s why places like Oberlin, and, frankly, Rochester are not on his list. While there may be plenty of opportunity to take composition classes at Eastman for UR kids, I’m under the impression that access to ensembles and private lessons with faculty for performers is a different story.
Maybe you can share your list on the music forum- or have you already? This comes up all the time, as you know. You are a real researcher and the info you have gathered is very useful. Good luck!!
If money is no object, you could look into UCSD. @Compmom knows a lot about the grad music program, but I suspect she also knows a lot about the undergrad program too. Also, UC Berkeley has CNMAT, plus great CS. There wouldn’t be any financial aid, but if you could afford it UC’s are open to transfers.
@menloparkmom - Do you think a transfer student would have access to composition classes at Thornton at USC? Do they allow non-majors to take composition classes? Or, perhaps they have some classes taught by the grad students? If you know more about access to the composition department there for non-majors it would be useful for those of us who frequent the Music Major forum to know so we can share that info down the road.
"Do you think a transfer student would have access to composition classes at Thornton at USC? "
yes. They do not reserve comp classes for those who have gone to USC since their freshman year. USC accepts about 1000(!) transfer students a year.
"Do they allow non-majors to take composition classes? "
yes.
see the link below
"Below is a list of courses that USC students, both music majors and students from other programs, may take as electives or as part of a music minor. "

here are other links regarding admissions deadlines for submission of music materials for those wishing to apply to the music program as either a freshman or transfer student
- THESE DATES ARE EARLIER than the normal USC admissions deadlines.

I noticed however that in this list for “songwriting and composition”- which is electives not core courses for a major- there are only “fundamentals of” and “basic” theory, and only the two classes for “composition for non-majors.” Also, “songwriting” is listed first so not sure what kind of composition this might end up being.
I wonder if a non-major can take lessons with the best teachers, participate in composition seminars for majors, take harmony and counterpoint, etc. etc. and have quality performances of works. Or whether any of the more rigorous theory and composition sequence would work for a transfer. Electives can be taken anytime, but the core courses for the major would be sequential and jumping in midway might be hard.
Here is the info on the composition program for a BM:
https://music.usc.edu/departments/classical-performance-studies/comp/bachelor-of-music-in-composition/
I looked up the info on those composition classes for non-majors - they are introduction to writing concert music - so classical. But it isn’t clear who teaches the courses. Or whether the more advanced intense courses are open to students not in the School of Music.
"I wonder if a non-major can take lessons with the best teachers, participate in composition seminars for majors, take harmony and counterpoint, etc. etc. "
No. one needs to be a music major or at least a minor to take those advanced classes. And that requires submission of the requiured Thorton application and dmissions material.
One cant take advanced engineering classes without being accepted into Vertibi engineering school.
Why would it be any different for the Thorton Music College.
It is a professional Music school, not just a music program with some basic music classes offered at a LAC.
The OP wanted a college that accepted transfer students, and offered great CS and Music programs in a warm climate,
“But it isn’t clear who teaches the courses”
Profs at Thorton or visiting music professionals. Grad students dont teach them.
These were just questions. I guess there is sometimes wariness about the kind of tiered situation with a BM program present, in terms of opportunities. At Eastman it seemed like the original poster was able to dip into Eastman’s offerings, though we don’t know to what extent.
BA programs in composition at LAC’s and universities go far beyond “basic music classes” and can often be better for a student like this than a program with a coexisting BM program. I think we were just trying to get to the bottom of that issue for that particular school- USC- since we think so highly of it
Hey - We lived in Rochester for 13 years. Finished an MD,Fellowship there, blah blah blah. Listen. I totally hear you about the dreary weather. Unless one has lived there, it is hard to imagine literally only seeing minutes of sun each day, at best.
Grey, cold, depressing. I actually didn’t realize how much it affected me until we left town. I had a whole new lease on life. That said, it was hard to leave Rochester’s nice people and sort of mid western values. Not to mention cost of living. Still, would make a different decision if I had to do it all over again. For sure.
Brandeis?
Wesleyan?
