My scretary just got this about the opening...

"We still haven't officially stated the grand opening date. They have several acts booked but haven't announced them and what dates their performing. With XXXXX arriving on the 18th he should be in good shape to attend most of the parties. We're going to have several events and not all the players will be invited to all of them. "

So it looks like events could start the 17th and go through the 20th but many will be via invitation only.
