Anybody been to Cancun? Anybody, Cancun

Which hotel resort did you stay at?  What facility you have at your hotel?  (Tennis courts, pool bar, water sport centers?)

I'm trying to decide if it's Cancun or Mayan Riveria

OMG, thanks a lot Utopia!

I'm considering Barceló Costa Cancun, have you heard of that place before?  Got any comments?  Their website looks nice enough, just not sure if the facility is really that great.  Here's the website: http://www.barcelo-costacancun.com/

There was a deal for Sens Cancun actually but when I checked, the hotel looks like Harrison Hotspring and they do not have access to beach....  On the other hand, Grand Princess Rivera is too expensive lor...maybe when I get richer.  But man, they have tennis courts, rock climbing, golf fields within the hotel, that gotta feel like a king already!

Got a few questions
1)  I know that most of the hotels don't have water centres, so where do you go to rent stuff?  Is it walking distance from hotel area or do you need to get a ride to somewhere else?
2)  What are some "Must See" and "Must Do" things at Cancun?
3)  Any tricks and tips that helps get around, or get "upgrades"?  (Like getting a nicer room by tipping the check-in counter, does that work?)

THANKS AGAIN!
