We are an older couple (age 60) with lots of energy and sense of adventure, but on a small budget. We're flying to Cancun late Saturday night and planning to take a bus to Chetumal (probably after a night in Playa del Carmen), but the rest of our itinerary is pretty loose. We know we want to go to San Ignacio and Tikal, and also Placencia or Hopkins. We are not interested in partying or the tourist scene -- so we'll probably avoid Ambergris Caye, but we would like to see ruins, go hiking, kayaking and snorkeling. So far, I'm interested in the Parrot Nest or The Trek Stop near San Ignacio and the Sea Spray in Placencia. Does anyone recommend any quiet but inexpensive hotels or activities that should not be missed? (And by inexpensive I mean around $50/night.) Is it possible to go snorkeling from shore? Do hotels rent snorkeling equipment, or do we have to take a tour? Can we enjoy Tikal in one day and without a tour?
Basically, any suggestions to enhance our budget vacation would be great!
