Stanford might be the ticket, but it is incredibly hard to obtain transfer admission. Thunk ailing the lines of 1-2%.
Miami
If you are willing to look at state schools in the Midwest or Atlantic coast, they there are some really good schools with spirited campuses with lots of sports and other fun activities:
Midwest:
Northwestern (aforementioned)
University of Michigan
University of Wisconsin
University of Illinois
University of Minnesota
Penn State University (not really in the Midwest, but…)
Ohio State University
Purdue University
University of Indiana (no Engineering major)
Michigan State University
University of Iowa
Atlantic coast:
Duke (aforementioned)
University of Virginia
University of North Carolina
Georgia Tech
Boston College
Wake Forest
University of Maryland
Rutgers
University of Florida
University of Miami
These are all quality schools that are either in cities, or which have vibrant social and sports scenes, or both. Most of them are similar to the University of Texas: big schools in cities with plenty of fun things to do. I just wanted to point out additional options. 
Miami is obviously the gateway to Latin America, but UMiami would be a fairly large step down from Cornell.
University of Maryland is pretty awesome
Vente a California!
large latin american population, large cities.
UCLA, UCSD, USC, Berkeley, Davis,
and Texas universities!
I understand exactly what you are saying!
Hi, I’m a freshman at Cornell too and I just wanted to let you know I feel the exact same way. I am really not enjoying Ithaca at all and and am actually looking to transfer to UT Austin too
i transferred out of cornell last year. i was a sophomore on the rowing and polo team. I was miserable: no time for friends, constant academic and athletic stress, and i hated ithaca with a passion. i joined an honors frat in a desperate attempt to make friends, but it only made my plight worse because no one there had time for friends either. my advice to you is get involved with the local town. most schools won’t take a transfer until after their sophomore year anyway. so here is my advice, from someone who has been through this and now constantly regrets my decision: get involved with ithaca, go to the park and read and make friends there or volunteer at an animal shelter/ get a job outside of school (part time) because if you base 100% of your life around cornell, you’ll be miserable like i was; there are parties outside of frats and greek life, join some clubs (frisbee and the ski team throw down!!); dont let yourself get caught up in your major. if i could tell myself these things this time last year, id still be in ithaca (well actually id be abroad). its easy to get caught up in all of the negatives about something. remember that when you leave, you’ll still have this decision with you. make a pro con list, and assign each pro/con an importance factor to help you make the decision.
good luck.
oh shoot another thing to think about when you’re transferring is what credits will transfer and how long you will have to be at your new school. i didn’t look into this enough, now i will be graduating 2018 at the earliest when i should be done with college in 2017. college sucks everywhere; but it does suck less here in colorado. if i had looked into this more, i would definitely not have trasnferred
also if you’re tall try out for crew it was fun and i got hella fit and they have good parties. even if you’re short you could still cox. okay good luck let me know if you want to talk more
If you want to go into finance, studying economics at Cornell will get your foot in the door very well, so you don’t necessarily have to go to a business school. If you can deal with the other problems (social, setting, school spirit, etc.), you should stay at Cornell. Obviously if you are really unhappy you should transfer out.
