Myself, I didn't care for Banana Bank. It was not very jungle-like for a jungle resort. The grounds were spacious and well-groomed. For whatever reason, I felt almost like a prisoner there and I couldn't wait to leave after our 3 days were up. I hated to see the animals caged and leashed as they were. My cabana, while unique, was so dark that I couldn't see what was in my suitcase. While the food was wholesome, I wasn't overly impressed with it either for the price.
If you are very observant of your Christianity, Banana Bank may appeal to you more. On a side note, I've heard that you can now get a beer there, but you couldn't when I stayed there a year and 1/2 or so ago.
I don't ride and so wasn't impressed with the horses either, though if I were a rider, that may have been a larger draw for me.
We took a couple of canoes down the river and that was very nice. Banana Bank arranged for us to go to Actun Tunichal Muknal and I'm certainly glad for that. Tunichal Muknal is amazing and I loved every minute of it.
The jungle lodge that impressed me was Jaguar's Paw . . . now that place is jungly!
A fish and a bird can fall in love, but where will they build their nest?
