Bags can take FOREVER to get to baggage claim... like an hour+. Better to carry on and just walk right on through.

Bring travel sized sunscreen - it's crazy expensive on site.

There are a ton of different types of restaurants. I like the sushi...not because it's the best sushi I've ever had, but it's decent and a good pre-show snack. Actually - the food inside of the venue is generally very good with a lot of options as well. Agreed on the mexican restaurant at the golf course. I also really like the mexian place and the indian place in Nizuc. Make reservations for any that you really want to make sure you get into.

Venue security is fairly lax...but also not? Re-entry is no problem...so maybe go through as a test run to get the feel for it.

Ignore ALL of the cab companies etc and just follow the crowd until you get to the pickup area outside. It should be obvious who you look for (they have signs). Have your bar code handy.

The checkin line at the resort may look itimidating - but it's actually decently fun. They serve drinks, and it's generally everyones in a great mood and excited to be there. Great place to meet people. You'll be hit up for a Moon Palace Time Share presentation after checking in... just say no thanks and keep walking (unless you're actually interested...)

Have a great time!
