Hi. We're thinking of going on the NCL Sky from Houston in Febraury. Two of its ports of call are Belize City and Roatan. Any recomendations for what to do there? Shore excursions are not yet available on the NCL website. Thanks! Note, there will probably be two families traveling with three children total, one 7 year old boy, one 5 yr old boy, one 5 yr old girl. Thanks.
