Need advice. E-mailed Herod about Island Delght tour since we've read so many positives about him on message boards. He qoutes price of $190 for 1-3 persons or $50 pp for 4 or more. Has anyone booked/reserved directly with him? We are traveling on Serenade of the Seas week of March 15, and don't want to book/reserve if there aren't more people thus making our price $190!!!
