$60k a year oos is a lot for a marketing major - that is a much less specialized program than engineering or biology, etc and the outcome school to school is more minimal. That is a huge gift your parents are being so extremely generous. But the marketing side of it also means how you feel about the campus when you visit should play a bigger role because it’s less specialized.
I’d look also at what is appealing to you about those school and expand your list. Check Niche for the marketing ranking, etc. most schools have merit clearly laid out on the websites or you can google OOS merit
With your grades and Merit you’ll likely find a number of programs in the 30-40k total cost range that are amazing and not waste 80k (bigger wedding? Down payment on a house?). More expensive doesn’t always mean better quality in the world of colleges - especially for a high stat kid .
