I've never stayed in a premium room there, but I've stayed in a standard room and the next time we go we're seriously considering paying the extra for the larger room.
The first time we went (2009) we were in a standard room and, although it was smallish, it wasn't too bad and I wondered why people always made a point to say how small the rooms were. I had plenty of space next to the bed closest to the door for my suitcase in this instance.
This year (2 weeks ago) we stayed there, again in a standard room. This time, it was VERY small. The queen bed nearest the door was so close to the wall/window/AC unit that I could not walk on that side of the bed to get into bed, I had to crawl in the bed from the bottom of the bed. Let's just say that this got pretty old in the middle of the night. There was NO space on the side of the bed for a suitcase, and we ended up using the table in the room for a suitcase because there literally was no where else to put them with four in the room.
I adore the CCI, I love how close it is, love the free shuttle and free parking, the boutique feel-- but next time, I will pay the extra money for a larger room.
