Well, we're here at YC and I'm up after our second night. DH and the kids are still sleeping away while I try and make some changes to our Touring Plans. I travel for work on a regular basis. I've stayed at the Ritz Carlton, Waldorf Astoria, Four Seasons, etc. When we stayed at Grand Californian 5 years ago I was shocked how GC felt like a huge step down from other similarly priced hotels outside of Disney. So I was prepared for that here at WDW.
But we really like the YC. Beds are very comfortable. (Yes, they're high but so is our bed at home.) Housekeeping so far has been great, as have general services. We got a tub/shower combo and it has a falling rain shower head that feels great. I'm not sure what I think of the hard floors. I think they're luxury vinyl so they feel a little plastic-y, though I don't mind the look at all.
The overall Disney overlay in the hotel is very subtle. I probably wouldn't mind it being a touch stronger but it's actually nice to come home to something less visually "in your face" since we get that in the parks all day.
We're in room 3089 (garden view) but if we sit to the left of the balcony we can see the lake and fireworks from Epcot. It's really a lovely room.
