I have not used this specific excursion so feel free to take my opinion with a grain of salt, but DH and I were in Cozumel a few years ago and the horses did not look so great. I don't imagine that the groups that run these operations make millions and I think the last ones to benefit are the horses. Any place I have been in the Carribean/Mexico etc I have always felt really sorry for the horses, and I really don't imagine their lot in life is very good. They are out in unbelievable heat, putting up with people pulling on their mouths and thumping down on their backs, shouting and yelling etc. I personally would not give my money to this type of excursion as I really feel it is cruel to use animals this way. I'm sorry if I sound "soap-boxy" but it's just my opinion.
