Use a suite upgrade to the (i believe it's called) ocean front master suite...it's worth it. Large room, hot tub outside on the balcony, bath tub inside, separate living space.

The club here is a JOKE. A boring, enclosed, square room with crappy food and unmanned most of the time. You really don't need to go out of your way to use this club. You're better off chilling at either of the bars right outside of the lounge.

Also, as the above poster said, the Hyatt Ziva Cancun is MUCH better than Riviera Cancun. The food is fine at both, and Riviera has lots of pools (though not much charm), but the breakfast buffet at Riviera can't even hold a candle to the Hyatt Ziva's breakfast. Same can be said about the sports bar at both.
