IMHO you should book with "Capt Marvin". I know there are now a couple more companies doing the tour there but this is the original. Also the locals use this company on the weekends. I know because a family relative spent two years working on this island and he took the trip monthly along with the local people. Next weekend I am cruising on the Grand and I am booked with Capt Marvin already.
They have been doing this tour the longest and they have a good rapport with the rays and also the eel and sand shark when they stop at the reef. I know I can't wait.
If you check their web site, they have started shorter trips now. I will be taking the 11:15 - 1:15 trip. It skips the Coral Gardens. Cost pp US is $29:00, a special for October - according to their web site.
Hi did the sting ray city tour in July. Booked on the ship. Never again. Everyone said go with Capt. Marvin and I didn't listen. We did have a great day, don't get me wrong, but we were packed in a falling apart old boat and that part was miserable. Our guides didn't know diddly. I was so mad at myself seeing all the smaller boats with less people. The people on this web sight know what they are talking about and I wish I had listened.
We're booked with Capt. Marvins for our Dec. 8 cruise on the Grand just because of all the great reviews plus (best of all) they are much cheaper than Princess' tour...made reservation online and Ruth at Capt. Marvin's will send you confirmation.......
