Depending on the number of people in your room, the amount to upgrade to a moderate hotel is less than upgrading your dining plan from QS to TS.
FYI - last year, the OP of that thread mentioned above was attacked because his information was not 100% correct and he has not posted since August. People on here can get testy!
Also, last year POR was excluded from
Free Dining, we assume because too many people booked it in advance, hoping to switch to Free Dining. But Disney saw plenty of rooms booked and decided that they didn't need to include POR in the deal since they didn't need to fill up the resort. So beware!!!
