Like Minniebeth and Drmomof3, we were also at the Poly for marathon weekend (for our pre-schooler's birthday, but not the marathon!) My parents were huge Poly fans, and I stayed at the Poly multiple times throughout childhood and have great memories of our stays there. Since then, I've stayed at BC, WL and CSR multiple times each, and CBR and Sports once each. So it was very sentimental to return to the Poly and we had a wonderful visit!
We booked garden view and only made one request on our reservation - either balcony or patio. We checked in at 11am and expected our room would not be ready until much later. The very friendly CM at the front desk asked whether we would prefer balcony or patio and I said "balcony." Then I added that if there is any way to avoid a parking lot view, that would be great. She made a call and a bit later, told us that our room was not ready yet but that it's a great room! She was right! We were in 3607 in Samoa overlooking the volcano pool with a beautiful view of the lagoon and the GF. Really wonderful. Great location near GCH and Captain Cook's for refills and we didn't mind the walk to TTC at all - it was very pleasant.
No problems with the monorail, CMs, service at Kona (lunch), Ohana (breakfast), the sushi bar (late dinner) or Captain Cooks (everything) - all were great. No problems with the room. I would not have noticed the "wear" on the furniture if I wasn't on these boards and looking for evidence of it. No concerns about cleanliness, mousekeeping, etc.
BC is our favorite resort and the best fit for our family, but we were extremely happy with our Poly stay. It's evident why so many BC fans also like Poly and vice versa. We have dinner ADRs in Epcot nearly every night of our trips, so the BC location works well for us. But the Poly rooms are quite noticeably larger, and my husband prefers the Poly room decor. I prefer the BC room decor, but will miss the Poly space. Our three boys are ages pre-school to pre-teen, so we like to walk to both Epcot and DHS from BC. While we still prefer walking, we had no difficulty with the monorail during our Poly stay, even during marathon weekend (and I agree with minniebeth that the Poly lobby was very crowded that morning!) It's tough to evaluate the bus service - we waited longer for a bus at Poly than we usually do at BC, but we didn't use the bus much so I'm not sure that's representative.
I'm happy to try to answer any questions! (And I checked both the gift shop and Captain Cook's for the string cheese a previous poster asked about - couldn't find any!)
P.S. As far as we could tell, the tiki torches were all lit at night. Maybe a more frequent Poly guest could detect gaps, but we could not - it was very nice.
Nice to see you over here!!!
Are you as anxious as I am for the August park hours to come out?? We need to look at our schedules in a few weeks and plan our meet!!!
But then we will have to wait another month for the September hours.
