Sounds like fun! The room is normally kept dark for the duration of the event, so there will be no problems viewing your holograms.
Looking forward to meeting you. Will you be in town on Friday night? If so, be sure to join us at the venue starting at 4 PM. We usually spend about 2 hours setting things up before heading out for our customary "pre-FLEM dinner party". There's a great Italian restaurant just down the street from the venue called Angelo's. After dinner, we'll be back at the venue playing with lasers until around midnight or so... FLEM proper kicks off on Saturday AM at 10.
