The 2 bedroom plus units are 1480 square feet, so larger than any of the other two bedroom type units. From the picture of the layout it looks like they have a huge balcony too. The 2 bedroom deluxe units are 1053-1280 square feet and the 2 bedroom presidentials are 1219 square feet. It says the 2 bedroom plus sleeps 8 with privacy for 6 but only lists one queen bed in the second bedroom. From the picture of the layout I see a sitting room next to the second bedroom that I'm guessing must have a second queen sleeper sofa in it. It appears that it would function very nicely as a third bedroom sharing the bathroom with the second bedroom and would be great for the kids. The presidential has two queen beds in the second bedroom but doesn't have the queen sleeper sofa in the living room and the 2 bedroom deluxe has two double beds in the second bedroom. Neither of them has that sitting room/third bedroom that the 2 bedroom plus has.
The 2 bedroom plus units are in the Areca Palms building which is in a good location in the resort.
