This is actually the back view of the hotel as seen when walking from the Pico de Loro Country Club. You can go to the Pico de Loro Beach Club via a shuttle you can ride at the lobby.
After checking-in at 12nn, you're given a room key card and a folio card (green card) which you can use to charge all your expenses (food, rentals, etc.).
There's a bar area and some lounge chairs by the lobby. This is where the breakfast buffet is set up in the morning.
