Guadalajara is a dope city to party in, just gotta be respectful and nice to everyone because a lot of people there have "connections."
Puerto Vallarta = lots of drunk Canadian bitches
Vancouver = coolest city I think I've been to. I would love to move there.
Sweden & Denmark = lots of eye candy, cool stuff to see, kinda expensive to get boozed up (Sweden has state liquor stores like UT, very annoying), but "alternative" supplies are available
Spain = really cool site-seeing. I was too young to party when I was there.
