Another vote for YC! Last year, we stayed at POFQ and then transferred to YC the day the AP discounts kicked in. I thought POFQ (not POR, but close) was great for a mod - it might even be my favorite mod and I have many good things to say about it. But I was THRILLED the day we switched to YC. I was so excited to make the move that we were up at 6am and arrived at YC via cab by 6:30am or so. Of course, our room wasn't ready, but we were just happy to be there.
The difference between buses everywhere at POR and walking/boating to Epcot and DHS from YC is huge. SAB is a pool that can't be beat. The dining options around the Epcot resort area and in World Showcase are wonderful. We don't do lots of CS, but there are a number of options in the area, including the BC Marketplace, Picabu at the Dolphin (full breakfast menu, open 24 hours and less than a 10 minute walk from the YC lobby - shorter from the room) and now the new Boardwalk Bakery. The YC lobby offers some light continental breakfast options and Captain's Grille is right there for a TS breakfast.
And then there's the balcony in a YC room - I love a balcony. It really increases the size of the room, and it's so relaxing at the end of the day after the kids are asleep, or when the kids have a few minutes of down time in the room. I so missed that balcony at POFQ and was happy to have it back at YC. And now we're getting down to minor details, but the room decor, interior corridors, comfy bedding and linens, peaceful lobby, rocking chairs out on the porch, views of the lake at YC . . . the list goes on!
