leave Sunday night. Just come for Saturday and Sunday. Remember, Monday is our closing day, and while stuff will be going on, our primary day will be Sunday, very much like SakuraCon's Saturday. Sunday will basically end at 3 or so when Closing Ceremonies is.
Just a thought.
I will say though, most people we've heard from love the date we chose, and choosing a date is nearly impossible because they either are completely unavailable for hotel space, cost too much, and even if you choose them, someone complains. Last year was Thanksgiving weekend... and yeah, it sucked in some ways, but it was what was available.
