The place was great, very quiet and peaceful (which was probably due to the fact that we had everything almost for ourselves). The staff was very friendly and helpful. What you need to keep in mind is, that it is more a hotel so if all houses are booked it will be a less private place than we had it.
What was a bit of a disappointment was the tour we booked with the hotel to Lamanai. The tour itself was great and the ride with the boat up the river was amazing. But when we booked at 7 pm we were told there would be only 4 people (including us) on the trip. The next morning, when we started it were 5 people (which was completely fine for us) but then we were driving really slowly up the river to make two more stops and picking up 20 additional people. Ending up with (by far) the biggest group at Lamanai and a really crowded boat with people sitting shoulder by shoulder.
