Take the tour to Chachoben ruins (check my spelling) if its offered....it's one of the nicer, unspoiled Mayan ruins.....it was just opened to the public about 4 years ago...its an hour bus ride from the ship, but worth it.
Your other options are to walk into Mahahal fishing village for some "local color" or hang out by the salt water pool and toss down a few Sol's (an excellent beer, better than Corona).
Its not the same beach because this one says its in the town of Mahahual. The Jungle beach break takes you by bus about 45 minutes to their beach so from what I've read, you are stuck in the middle of now where.
I like the idea of being in the town so we can walk around and explore and come and go as we please.
The email they send said that the port controls transportation and they charge $3 to take you to Mahahual and then its a $2 taxi ride back.
Chiquita - I gather you are booking this? I think I like this better than the cruise lines one.. you are right about having the town there. So it's $3 each to the beach, and a $2 taxi back? is the $2 per person? Either way, 25+5 is 30 .. 9 cheaper than carnivals...
We also really enjoyed the Chacchoben ruins... great tour! Depending how long you are in port, there may also be enough time to visit Mahahual, then return to the plaza for some shopping and watch the dance show they put on there. Theres also a restaurant in the center of the plaza and a real nice pool (although salt water, Ive heard), nearby hammocks, and a beach within walking distance. We made our way out over the rough, rocky bottom and did some snorkeling, it was fantastic.
Bummer about being changed from Belize to Costa Maya. We went cave tubing in Belize and loved it. (we took our own excursion instead of the ship's and were able to tube through two caves instead of one.)
In Costa Maya, we brought our own snorkeling gear and took a taxi into Mahahual. We walked to the other end of the town and found a nice beach with another couple from the ship sitting there. The owner of the food/beverage stand across the street served us margaritas and chips/salsa. We snorkeled, ate, read books, and sat in the sun, and visited with our new friends. The farther you walk away from the taxi stand, the town gets poorer. You could see the ship from the beach we were at, but it is not walking distance.
I wish now I could have read the post about the schools. I never thought to bring school supplies...what a great idea. The website and pictures are great. I will definatley do that next time we dock there.
