Hey Vicki! You must be cruising after your NY stop?

Been to all of those islands on cruises on NCL--good advice for cruisecritic.com but have no idea who has a zipline at those destinations.

Guide/drivers are all in the ports--some are licensed guides--most are not. Go past most of the crowds and don't be concerned about turning one down for another--ask about AC in cars, too. Often the car is nowhere nearby--you have to go and get surprised by whatever the car/van is. Some give a great price then you find yourself waiting until driver gets more pax--just be aware.
We found great driver outside the port gates at St. Lucia and same in Barbados. Unless the laws have changed all beaches in Barbados are public, so you can access them thru hotels and rent chairs/get served at some of the finest on the island.
Antigua is small--some nice beaches but not much else that you can't see walking around St. Johns--lovely old church etc.
I'm not a fan of St Thos at all--I go straight to St. John via Redhook Ferry to my fave beach--Hawksnest, but you can just go to the National Park, too and snorkel (it has facilities+entry fees) There's supposed to be good hiking on St John but it's always too hot for me (and uphills are not my heart's friend)
I adore Orient bay at St Maarten (french side--fave beach bar is the continents where Roy works--everyone should know him?)
Not much else to see on that island--butterfly place and salt beds bore me but some people really like that. Town of Marigot is interesting for people watch (many are nekked!!) Most drivers can give you the history tour on the way to the French side.
Bon Voyage!!
