It is open. It's not 100% operational yet, though. Several pools are not available as promised and I believe some restaurants are not yet open. I don't think the upper rooms are completed either. I know a lot of folks staying at Maho are complaining that they've had amenities taken away from them for the OP guests. There is only one pool available now and they are using The Palms restaurant as both the grill for lunch and then change the menu to ala carte for dinner, but it's still the same restaurant. They've also said that OP guests get preferential seating at the restaurants while Maho guests have to wait. We booked Maho for May after staying many years in a timeshare, so I'm hoping our expectations are less and we won't be disappointed. We figure we'll probably eat our dinners out at least half of our stay anyway. I hope they are not driving their Maho regulars away by trying to just keep their OP guests happy.
