Pick up time is up to you, but we have found that 7AM - 8 AM works wellIn Tulum you can hire a guide for a tour or just explore the ruins on your own. 2 hours in Tulum is plenty of time. Tulum is open from 8AM - 5PMThen go to Xel-Ha where you can swim/snorkel, float down the lazy river, walk through the jungle, eat, drink or relax in a hammock.Xel-Ha is open 365 days a year from 8:30 AM to 6:00 PM.
