If you can afford to stay at the Presidente, afford yourself one of the boutique dive ops that store gear, have fast small boats, use larger tanks, and will pick you up at the Presidente dock. That's my opinion.
(When I tried Scuba Du once during my one and only stay at the Presidente back in 2000, dive briefing was "25 min at 80 feet, second dive 40 min at 40 feet" or something like that, complete cattleboat experience; I understand things have changed since then and they're more competitive with the cattle-free dive ops, but please keep your mind open to the many dive ops that will also pick you up at the Presidente dock and may offer attractive alternative services and even pricing compared to the on-site op.)
