Turneffe may or may not be OK with 3 kids. Depends on the ages and how good they are at keeping themselves occupied withouit a lot of amenities. There is no town or village on the island. Just lots of sand & water!! Great fishing, snorkeling & diving. The packages are either 3, 4 or 7 nts only. No day trips from AC unless for diving. I have done trips for clients with kids who loved the remote atolls. I would never take my 3 kids there (unless it was without me!!! They would drive me crazy). It depends on the kids...and you.
