Eric/Lisa will not be there. Matt was there with his girlfriend; Gary & Marcy/Ron, based on their on-screen character, sound like teams that will forgo everything until tomorrow. Sam/Dan & the GT: guess they couldn't make yesterday's festivities, but sound like team that will show up tonight. Last season, some people came in Friday, a few more on Saturday, and then the rest (that could make it) on Sunday. So it varies.
Of course, S/D are more likely to show up than FT/BE (since they're F3).
However, no Eric/Lisa, which isn't a surprise since they're so irrelevant. Good to know why Canaan couldn't make it, and Mika had her Wisdom Teeth removed earlier in the week. Sucks about Maria falling ill; she was all ready to come and all (and I actually thought she was already in New York). Maybe they'll make up their miss in the more popular spring TAR reunion in about 5 months from now.
Anyway, thanks for sharing! I have to mention: this is reunion stuff (meaning I couldn't tell you everything). I'm only going to the Main Event, though similar to everything, I won't know who shows up or who showed up until the event(s) unfold(s).
