The Bahia complex is great. We stay with this chain almost exclusively when we travel the Caribbean as we find it to be excellent.
The Kontiki cruise is a blast if you are looking to get off the resort. It’s a double decker party boat where drinks, snacks are included. You go snorkelling for a while then the crew does skits and gets everyone dancing on the way back. It’s a half day excursion so you aren’t wasting a whole day off the resort. You can book this tour right at the resort.
The Bahia has loads of shopping in the various lobby shops or in the Pueblo Principe located at the front of the resort. There’s also a beach market about a half hour walk along the beach (turn right facing the ocean). You can haggle with the beach vendors to get a better price.
As for drinks…the beer of choice in the DR is Presidente which is really good. Very easy to drink in the warmth of the Domincan sun. Cocktails are better in the lobby bars as opposed to the beach or swim up bars…but they’ll make you pretty much anything you want.
Enjoy your Holiday.
