Norma called. Officially, they have a no guest policy. Don't know how it is unofficially. I'd assume if it's as busy as Oasis in previous years, they'd get more strict during this march as well. But who knows.
I can't imagine a better Spring Break experience: you bring a hot girl back home and she gets denied accessed to your room. That sucks big time. Where do you guys make love in Cancun?
no such thing as making love in cancun its straight f***ing Try the beach (jk that will get u arrested and yes it happens)
Like Nuno said, get a non all inclusive hotels and you will be fine. Hot chicks can come to my room freely without having to worry about being stopped by the security.
Also when encountered by security money usually smooths things over. At krystal i walked in around 3:00 no problem but by 4:30 when i left they had some security at the entrance. It all depends on the situation you know and the time.
things at Krystal will change due to SC HQ thingy, for now they say that guests are only allowed at the lobby bar, no where close to the rooms, they will get even worse during spring break... mark my words
