We love POR. That said we stay there in the warmer months because of the quiet pools. We thought it would be a treat for the grands, with the pool slide. They didn't think it was very Disney, so this next Feb trip, is over to Pop. We have no trouble going "backwards". If Mousesavers has a code that makes the mod's only $5 more than a value, the savings isn't as good as you think...since you can usually use that same code to get the value for less (I assume these people didn't check to see what the value was with the same code). Often, with the AP and postcard codes, the values are $49 and mod's $74 - 79 during off times. With the everyday codes, the values are $55-59 and the mods $79-84.
It's just an individual choice. In three weeks, we'll be staying at Pop, and it's my sister's first trip ever, so we think she'll love Pop, more than she would POR or another mod, since she is looking forward to blantant Disney LOL. With the $180 savings each room, we can do a lot of eating.
