This convention was run in the Sheraton Surfrider, a big hotel right on the beach.
It was attended more by people not going on the cruise, but had the same guests.
Chase Masterson and Lolita Fatjo can be seen at the rear of this shot, and Manu Intiraymi and Wil Wheaton almost in the picture, left and right.
I forget where these characters featured in Star Trek.
Wil Wheaton and some fans.
