We are arriving on a cruise ship in St. Kitts on 12/24 and want to spend our day on Nevis. 4 of us ladies want to do it on our own rather than the cruise tour. Our plan is to take a morning ferry to Charlestown, lunch and beverages on Phinneys Beach (must have a Killer bee!), hire a taxi/tour guide for about 2 hours and be dropped off at Oualie Beach to take a water taxi to I believe Turtle Bay? Then taxi to the ship. Our ship departs at 5pm. The ferry schedule for the return to St. Kitts doesn't seem to work for our time frame, but taking a water taxi seems like a nice change. I've read that it should be about $100 for the 4 of us? My problem is...do I pre-reserve and with whom and how? Or, can we just arrange it that day? I'm just needing to feel confident that we will be able to get back to our ship on time. Any help out there? Thanks in advance!
