Welcome!!!
You must be SOOO excited about your trip!! I think planning to see Chichen Itza, Tulum, and Xcaret are wonderful choices. Are you planning to see Chichen Itza on a Playa.Info tours?? I hope so.... as they really do a great job in making it a very special day for their guests! Your jaw will drop wide open when you first see El Castillo (the "pyramid") in person. It's a fantastic and fascinating place to visit.
As for your English, it's
wonderful, so please don't hesitate to post more.
