Hi there
I learned how to dive with Dreamtime when they were still operating as Blue Ha and it was the best three weeks of my life. Ive checked their website and they seem to have grown since I left a year ago (now they can house guests on the premises), but I cant picture them becoming a big operation overcrowded with «boat people». Instructor Jono is extremely professional and safety-oriented, and both he and Tanya are very nice and ecology-conscious people. I regularly look for reviews on them on the Web and theres only great feedback. And you wont regret your diving in Mahahual. I just came back from the Red Sea and it was quite disappointing to see how damaged the reefs are. Ive seen much nicer corals and sponges in Mahahual. Besides, the reef is so close from the shore that you can also swim and snorkel on your own.
As far as life outside the water goes: well, theres not much to do in Mahahual, its all very quiet once the cruise ship leave, but thats whats so charming about the place. If youre planning on diving everyday, you might want to stay at a place close from Blue Ha, as there are only 3 buses a day driving along the coast road (at least it was the case a year ago). But there are many taxis and its very safe and easy to get a ride from the locals (whom include many expats). I stayed at Travels Inn (km 6, about 2 miles from Blue Ha), a great and inexpensive place owned by a sweet Dutch-British family, and never had trouble getting into town.
If youd like more info, just let me know, I so love this place I could keep on babbling for pages.
