Our family group of 7 stayed at Posada Jardin in Ticul for 3 nights in March 2010 and we highly recommend it. We rented all three cabanas at a great rate. The grounds are spacious, well treed, very relaxing and easy walking distance to El Centro.
Roman is a retired engineer and math teacher as well as a very gracious host. He has a website in Spanish.

Ticul is definitely NOT a tourist town, which we really enjoyed.
