We did Lamanai with NCL and had a great day! The bus ride going was interesting because the guide talked most of the way. The riverboat ride out and back was for me the best part of the the excursion. We didn't see many animals (I'm still not convinced the one bird wasn't an animatronic) - but the scenery is beautiful and the ride was fun! The boat seated about 30, but it moved. We had an hour in the ruins. All that said - while I'm very glad I did it, I'm not sure I'd do it again.
