I will be in Cayo in a few weeks with my 10 year old. We'll probably rent a car. We'll be there for 4 nights. Between San Ignacio Resort, Chaa Creek and Caves Branch--which one would be best for us? Or does it make sense to do 2 nights at one and 2 nights at another? We of course want to see caves and ruins, and then want to have a nice place to come back to. Thanks in advance!
