the bavaro splash is an older company, operating many years in the area, they run as a company different watersports activities, like parasailing, that mentioned caribbean festival snorkel trip and a speed boat excursion. they do their pick up by trucks, the same kind of truck beeing used on truck safaris, have frinedly staff, so if you want to do that kind of activity that company would be agood choice.
for the snorkel stuff there's also an other one, named the Marinarium, you'll find their representatives near the front desk area of the resorts, or ask your tour rep about them, it is also a several hrs excursion, pick up in airconditioned modern vehicles, their boats, i think it is 4 big catamarans at the moment they operate, are always up to date, they work really professional, snorkeling, animation, nurse sharks, stingrays aso.
have fun
