After a lot of research and reading these boards, From what I understand, a passport is not necessary to cruise the Eastern Caribbean (tortola, st. thomas, castaway cay). My daughter's "child" passport expired in 2013. We are looking at taking a last minute cruise (May 7th). She is now 18 years old & to get a passport through "Rush My Passport" service it will cost right at $500. (Yes, I am ready for the flaming). We can either pay for that & she have a passport, use her birth certificate & valid driver's license, or not go at all. We'll I am not particularly find of the last option. So, has anyone reading this cruised using a birth certificate & valid ID recently? I am correct in thinking that we can cruise using her birth certificate & valid ID correct? TIA!!
