Hi
We did the Epcot one in May - on Mothers Day to be precise - and it was thoroughly enjoyed by all of us. There were 10 of us altogether, plenty of room in the boat and we parked just under one of the bridges to get a fantastic view of the show. Best bit of all though was not having to join the rush of people heading for the exits and car parks - just a nice leisurely cruise back to the boardwalk.
