Again too many to list but I'll try.
Wildlife...monkeys, bats, caimans, tarantulas, sloths, butterflies, frogs, toucans, parrots, etc
Food...tried many of the local dishes, fruit, coffee, everything we had was amazing
Accommodation...loved, loved, loved all the choices. Every hotel was very different but all were incredible
All the staff, at the hotels, driving the buses, at the restaurants...we really had no bad experiences
