1) No, we do not allow this.
2) I have been asked several times for celebrations of anniversaries, birthdays, etc. *
3) There is not enough time between shows.
4) The first show has CM's schedules too close to the show time to allow folks to enter.
5) Your option would to be first in line and decorate before the others enter the room.
6) Going to be awfully tight, but it might work.
7) Of course, you would miss the group picture.
* Can you imagine the confusion, if we allowed this? EVERYONE would want to get in early to decorate a table under some pretense or another. It would be unmanageable.
