trying will never hurt for this particular case. especially when the final decision will result having you be in one location for four additional years, and then some.
check out cornell and see if you like. a few extra hundred dollars and few extra hours to check out a school definitely puts any future regrets and headaches to rest. but even with that, stanford is great place to be.
congratulations on stanford and hopefully you will make the right decision to take or drop the invite!
