We were going to Tikel however why go there when I have to have knee sugery - want to climb the Ruins and Ruin 4 is out - we'll go next year.
However, these are some hotels I found to be great:
Hotel Santana, Peten Esplendido - also the Jungle Lodge would have been terrific except I'm not an outdoor type of person (mosquito nets, etc.) We would have flown from A. C. to Flores via Tropic then Flores to Cancun.
