I was thinking the same thing about people giving others a chance, naturally since I'm one of the people who has been completely shut out so far. Then again, if I put myself in someone else's shoes I guess I could see the temptation of going to every event I could get into to get pins, prizes, etc, even if I had already got in before.
I think it would be better if there was some way for vmk to moderate how many times you were allowed to go into a host room if so many others are getting shut out. Or, like I said before, if they could open one more room at the same time or offer the same event at a completely different time of the day that may help out tremendously.
Maybe now that dc is gone they will start considering solutions to this because it definitely isn't fair for some to get in multiple times and yet one person to try and try for the entire two hours to no avail.
