They dock very close to the main st in St Johns. There will be dozens of taxi vans of all sizes & a favorite trip is Nelsons Dockyard, Shirley Heights, a drive through the Rain Forest & then stop off at one of the 365 beaches (one for every day of the year) for an hour or so before returning to the ship. This is a great way to see Antigua & we still had time to walk around the town to see the local way of life. This in my view is the best way of seeing Antigua. A small taxi van can negotiate the narrow roads & streets far better than a 56 seater & of course you can stop/start/move on at your pace without waiting for the inevitable stragglers that pervade every coach journey. Finally the price, work on about 30% of the cruise tour & you should be about right.
Good Idea but try to share with another couple make sure the thing has air con agree the price and pay at the end ,Shirley heights is breathtaking.A short walk into town may get you a lower fare still Enjoy?
Buckley's right about sharing, but the local Taxi Mafia Boss does a lot of the negotiating & he will try to find likewise couples or talk people into filling a few more seats if he can.
