The Hamaca serves Presidente beer.
As for exploring off hotel grounds, the Hamaca has single-speed bikes with chain brakes. There are bike tours every morning, where they show you local places of interest. You get to ride across the Boca Chica beach back to the hotel.
Some tips: Get to the bike rack a little early to ensure getting a bike with fully inflated tires and meaningful tire tread. Also, when riding, be alert for the motoconchos on mopeds and motorcycles who zip by on the narrow streets of Boca Chica. Finally, the roads, though adequately paved, are sided with narrow deep storm channels for rain run-off. You don't want to ride into them.
You can also obtain a bike without having to go on the tour, but I recommend the tour first. I almost forgot -- It gets HOT and humid early, the sun is very strong and I recommend taking a hat, a backback and a water bottle.
Have fun.
