FH and I are hoping to have our ceremony and reception on a private yacht that goes around Boston Harbor. They take care of pretty much everything (food, decorations, entertainment), but the ceremony is an hour and the yacht is chartered for a three hour reception. If we're only having about 50 people for a lunchtime cruise, and most likely will not be having too much extra stuff like readings, do we really need a three hour reception? I feel like four hours on a boat might not be too appealing to too many people, but the site has the fee set at three hours for all receptions.
