Are you in a studio or a larger unit? The studios used to have a heavy drape to pull across the patio doors, but they were removed in the rehab a couple of years ago and replaced with those Roman blinds. I liked the drape much better, too. The front windows for the studio should have blinds AND drapes, unless that changed recently. In the one bedrooms, I think there was always just Venetian type wooden blinds in the living room, but there should be heavy drapes in the master bedroom.
We were in a studio. Either way not having darkening shades covering that area of the doors is a problem though, since the kids sleep in that area if it's not a studio, and if it is it affects all of us! I guess we will just plan for no sleeping in when we stay at OKW!!
Overall, we were really happy at OKW and looking forward to staying there again in December!
