So many of those reviews are dependent on the person's attitude, the circumstances (e.g. the first week a massive hotel opens). There are many complaints about delayed check-in. I stayed at RPR last fall and checked in around noon, planning to head to the parks for a few hours because, as I figured, the room wasn't ready. Came back at check in, still wasn't ready. Went to the pool and waited several more hours for it to be ready. Meanwhile I've stayed at CBBR twice this year, and each time the room was ready around noon.
In the end, I'm down there to vacation and having to wait for a room doesn't really register with me - that's what bars, pools and a massive theme park are there for!
