We’re staying two nights in the Hotel Ventanas al Atlantico in a suite with a balcony looking out over the pool and ocean. It’s a gorgeous location on a nearly deserted beach but the room was a little run down (squeaky beds, no light in fridge). It doesn’t supply anything (paper towels, coffee, shampoo) so you need to prepare accordingly. We found a small supermarket behind a pharmacy just down the street where we could buy ice, eggs, bread, and bug spray for the noseeums. 
The next day the boys chose to relax and enjoy the ocean rather than head out on an eco adventure (which the area is known for). For lunch we ate at a barbecue restaurant a mile down the street that the boys swear has the best Mac and cheese with burn tips ever.

Also 7 arches on the ocean. The cliffs are sharp volcanic rock so shoes are a must.
Unfortunately we never made it here because
For our last day, I managed to get reservations for the Rio Camuey Cave Park by emailing Cavernasdecamuy@drna.pr.gov It took several weeks to hear back but we got 9am reservations. You need to arrive 30 min before your booking, wear closed toe, rubber sole shoes. The tour takes 1-2 hours
The caves were fascinating but significantly impacted by Hurricane Maria, which flooded the caves with mud and knocked out the power that once illuminated the walls and formations. It’s harder to take pictures but seeing the cave illuminated only by flashlight is magical.

Unfortunately we never made it there because the day was too hot and we had to check out of our hotel to head to the airport in Aguadilla.
