I don't know! We're going to have to get in touch with her and see what she recommends. Any advice welcome!
Poker Run is a lot of fun, but can get pretty wild. If you are looking to avoid that, I would recommend grabbing a ball at BEYC. I wouldn't worry at all about being able to get a mooring ball over there. Most of the 'go-fast' boats that participate in the poker run come up for the day and if they spend the night they will be on the dock, not on a ball.
I would call Elaine directly and ask if she would be willing to pick up you from the dock at BEYC for Snuba. She may be willing.
