Relax everyone. The same "crowd" issues happened when VMK went "live" from beta, when first phase of Tomorrowland came out, when Frontierland and Haunted Mansion came out...it always takes a couple of days for everything to settle down. Keep in mind that almost all players are descending on Tomorrowland and that is really stressing the rooms and servers. The frequent closing is just a part of it. The games and prizes will still be there and, while I know everyone really wants to play, give staff a chance to do the necessary tweaks. Programming games and graphics is really a complicated process. There is a lot that goes into it and, while a programmer can make certain assumptions, not all programs respond as expected when hit with massive VMKer "Ooooo, looky here it's NEW, I have to do it NOW" issues.
For myself, I am really looking forward to it but, I'm off to play Kingdom Hearts 2 since I really don't want to be aggravated doing something that is supposed to be fun.
