Funinthesun,
Which Holiday Inn are you referring to? The Holiday Inn Beachside has been torn down and condos are being built in its place and the Holiday Inn La Concha has a small pool but not really a place I would consider a great place to hangout over SB. Plus I think they might be strict with only guests staying there can use it. I believe the old Days Inn (at the start of the island) is now a Hoilday Inn but the reviews on it are not the best.
