How many do you intend to have there?
We were married on the Latitude 43 Degrees that can take up to 10 people. You get your choice of where you want to be married on the lake depending on where you are picked up from. We decided on Tuftonborrow in front of all the Marriott Estates. It was a sunset wedding and wonderful. Renewing your vows could be just the same - a wonderful time.

I just checked the web site and they have decided to stop doing charters.
