We stayed at the Mayan palace, went to Tulum, and went Chichen Itza for the spring equinox - great beach at Tulum! Next time Xelha and Xcaret when my daughter is old enough to snorkel.
Quick Tips:
Take peanut butter, cheese, and coffee for quick snacks and easy meals. Eating out is not too expensive but is tiring with a three-year-old all the time.Best Way To Get Around:
We took shuttle buses and tours. The one day I rented a car was so much easier. The next time I'm in Cancun I'll rent a car for the whole week.
