Hi,
I just got back from 8 nights in a kids suite. You can check out my photos of the room here:

The room was VERY nice, we loved the decor and the bright carpet

Everything was so clean. We were in room 1702, on the top floor, next to the elevators in building 1. The freeway noise was not an issue for us - we slept with the airconditioning on anyway, so that blocked out the freeway noise.
There was no treasure chest or wireless internet in the room (there was wired internet and you can get a wireless signal if you are near the lobby), but we knew that ahead of time. Housekeeping was great and the room was always cleaned very quickly.
The beds are extremely comfortable and even my girls loved their bunk beds. The sofa bed in the kids room was a true twin size. The wall-mounted LCD/Plasma tvs were a really nice touch as well and we also enjoyd the fancy coffee machine (flavored coffees and hot chocolate pods are available for purchase in their store).
Any questions, just ask
