A Yacht party price depends on many factors. Here at Thames Party Boats, we give you a flat rate of the boat, this changes according to the date and time you would like to use it. A Yacht party price would include things like a DJ, partly paid bar (maybe), food or snacks for all your guests, any decorations as well anything else you would like. Therefore, the Yacht party price will all depend on the extras you would like to add to your booking. The yacht party price we give you is for up to 210 people; you can have as many to as little as you like if it is not more than 210 guests.
