They don't usually announce the Pop Warner schedule until the Fall, because I don't think they know how many people they'll have until the football season is under way.
Most frequently in recent years, they have stayed at the All Stars and POR. I don't know why they stayed at Pop last year, but I know they stayed at CBR instead of POR because POR was undergoing renovations. This year, the POR renovations will be complete by then but now almost 500 rooms at POR will be Royal rooms which I doubt will be an option for Pop Warner. So because of that, I wouldn't be surprised if CBR is now the moderate choice hotel each year. Plus, there's a rumor that POR really hates the Pop Warner crowd and has been trying to get out of them staying there.
