Yeah, the cavetubbing and zipline are in Belize using Major Tom's excursion. Honduras is supposed to be out of this world, actually going to a private island made on a reef. The reef is in about 5-10 feet of water so should be exceptional.
Man I hope you wrong about Cozumel, I know the shore snorkeling is supposed to **** but I'm paying for a boat excursion. From what I've read the palancar reef is supposed to be one of the best in the world. If it's overrated then I'll skip spending the extra $$ and just drink at the beach.
