The lady I spoke with at Disney was under the impression you only get robes in the cat 1, 2, & 3 staterooms as well. That just seemed odd since you are in a deluxe resort with a cat 4 & 5 stateroom and of course the deluxe resorts have robes. I agree that I will want a robe, ours are just so bulky and we are quickly filling up our luggage. We have found that the need to take a wide assortment of clothes is about the only drawback to going this time of year. ( Of course it was a lot easier when DD only took T-shirts and sweatpants, but those days are gone forever, lol.)
I will report back upon my return, I have lots of memory cards and plan on giving the new camera a good workout as well!
