Just got off the phone with the carnival's cruise consultant asking for prices for all the shore excursions for St. Thomas and St. Maarten. He said "That the prices where subject to change, and that all excursions range between $20 and $100". THIS WAS NO HELP TO ME. I was going to compare these to ones I can book myself, but since I don't know what they are charging, I guess I cannot compare.
Anyone with an answer to my problem, please let me know.
