We stayed in a refurb'ed room in November, Car Suites Building 3. The storage underbed is very nice to have. Unsure if the television was also a part of the upgrade as well, because since being home and watching YouTubers, it seems non-refurb'ed rooms have a smaller sized tv.
Why was I looking for videos? We hated the hard rubber mat flooring in the room. At that time we were totally unaware of refurbs occuring. So I scratched my head at the flooring in the room. It made everything so loud and echoey. With excited kids, it made it even worse. I swore to my wife it was carpet when we stayed in 2013, so I went searching online once home and sure enough the flooring change is in the refurb. Only then I realized we had been in a refurbished room. The old carpeting was much more Cars themed than black rubber matting.
Skyliner is a game changer and I recently did some AoA pricing for my sister's family by calling the 407 Disney booking number. The CM on the phone said Skyliner was driving much interest in the hotels on the Skyliner route. I believe it.
