Differences. Many more boats, many more mooring balls. More restaurants. Still wonderful! Biggest difference for us has been the addition of cruise ship passengers at the more popular spots. Not sure if they are still stopping at BVI in June.

I do know that they are welcoming a 4000 passenger Norwegian Cruise Line ship on April 29 to inaugurate the brand new cruise ship pier, the same day we set out from Moorings!

Without knowing what type of boat you are sailing, it is hard to rate the AC. Some boats require you to be hooked up to electricity at the dock, some don't. From all I have heard, it is a wonderful addition to summertime sailing.
