I am leaving for Cancun on Sunday and was hoping someone could give me some ideas on the night life and great places to eat.

Here's a great resource:

Cancun Tourism - Cancun Vacation Reviews - Cancun Vacations - TripAdvisor

Enjoy your trip!

I went to cancun about 3 years ago. I was pretty young so I didn't do much of the night life. But... There is a really awesome exotic park called the xcaret. Awesome place. You get to spend the whole day there, and there is everything to do. Snorkeling, swimming with dolphins, floating down a river, A big buffet for lunch, Exotic animals! Check it out online!
