Hello, We are planning to be in Valladolid for 4 days and thinking of spending the next 3 days on the beach. My son's girlfriend has to fly back to the States. So we are thinking of taking the Ado bus back to Cancun with her. I would love to hear some great ideas of where we can stay the next 3 days? We have two active boys and would like to do some snorkeling, visiting ruins, hiking, etc. We don't like to sit in the beach for a long time. Thank you.
