I'll be in Antigua on a stop on the Carnival Destiny this December and would really like to visit Turner's Beach and Devil's Bridge. I'll be traveling alone and can book a 3 hour island tour with Lawrence of Antigua for $50 which includes entrance to English Harbour, Nelson's Dockyard, and Shirley Heights as well as a stop at Devil's Bridge. At the end of the tour, I can get dropped off at Turner's Beach and he will come back to get me at any time I wish.
My question is would it be less costly to jump in a taxi by myself and have them take me to Devil's Bridge and drop me off at Turner's Beach and then catch another taxi back to the ship? Would it be foolish to miss out on the island tour of Antigua? I like to see everything I can in the places I travel to, but from what I've read there's not much to see on Antigua and the beaches are the main attraction.
Thanks for all of your input!!!
