We're going to PB Emerald Bay in a few weeks. Two young families. Kids ages 9 mos, 1 year, and 4 yrs. Any advice on things to do? My wife and I have been before we had our son. So we know the hotel, we know the trip into the city, etc. But what about things to do with the kids? Are there any harbor sails that will allow us with younger kids? The zoo/aquarium? Or should we just stay at the resort. Any thoughts are greatly appreciated.
