It's not official until the Fall when the Pop Warner schedule is out. It is typically the first full week of December arriving on a Saturday and leaving the following Saturday. For 2012, it will likely be Saturday December 1st through Saturday December 8th, but that is speculation my part.
The resorts will be harder to guess this year due to the changes at POR. In years past, it was typically always the All Stars and POR as the host resorts. Due to the POR refurbs this past year, it was CBR instead of POR and I also heard POP instead of the All Stars but I don't know if that's true and if it is, why they switched it to POP. Since a lot of the POR inventory is now Royal Rooms which are an upcharge, I would not be surprised if they kept CBR as the host hotel this year too. It will provide more standard room inventory, and plus CBR is in need of a refurbishment and the word is that those Pop Warner kids can be rough on the rooms. Just speculation again though!
