I was wondering myself what is the difference between and standard and deluxe AND between a deluxe and a villa room. We had a small balcony, but it was garden view. I was wondering if that is still a standard room since it seemed that there weren't all that many balconies.
I decided not to make a request for a particular wing and see what I got and how I liked it. Before, leaving, it was my understanding that west wing is more convenient, but east wing is quieter. We were placed in the east wing. It was more walking, which I don't mind. I think if we return with our DS, who is 4, I would probably request west wing so that it wouldn't be as much walking. It was very quiet where we were in the east wing. But, I don't know if it would have been less quiet in the west wing.
Another thing I noticed about the west wing... it appeared to me that the west wing is smaller that the east wing. Does anyone know if this true and if so by how much? So, if this is true, my guess would be that you can request it, but there may be a chance that you don't get it.
We did not experience the concierge. I booked a standard room at the entertainment rate for $155. Especially at that rate, I felt like we got more than what we paid for!
