WDW's ticket price to the public hasn't gone up. However what they are charging ticket resellers like ParkSavers/Expedia could have. The 7 days for the price of 4 at $394.46 lasted for at least a few months but it was a promotion. They obviously could launch it again but I doubt anyone here knows for sure.
They are still advertising it as 7 days for the price of 4, which is why I was wondering if WDW's prices had gone up.

I also upgraded 2 of them to APs and again, ZERO issues!

FWIW, it was a big deal for me to go from staying at BC to trying POFQ - which I ended up loving. It took two years to convince myself I was ready to try POP (and now I'm actually looking forward to my first stay there). I had to get really sick and tired of having issues with American Eagle at DFW before I finally flew Delta. Like I said, I'm resistant to change.
