We stayed at the RIU for 3 nights. Our room was 714 and it was a partial ocean view, on the other side. Although we didn't have the pink hotel building (part of Atlantis) we had the gorgeous view below our balcony of the hotel air vent system and air ducts.
I noticed your previous post asking about the hotel. We enjoyed the hotel staff and services. Overall the food was good, the hotel lobby/pool/restaurants were well staffed and regularly cleaned. The rooms were not as clean as I'd like but then again the floors are carpeted in the rooms so the musty smell is a given. The room was cleaned well before our stay. Keep everything in your safe. A couple we travelled with ended up with a room assigned to someone else so to avoid any lost items, keep everything locked up (we've always done this).
When are you going? Have you booked?
I suggest you opt for all inclusive since it is the most economical.
