Assuming the original poster is a CASH guest - since he's considering the Contemporary as well, he absolutely WILL have daily housekeeping.
I'd consider the size of the party. For a couple, the VWL studio would be fine. For a couple with a kid or 2, the much larger garden wing room at the Contemp would be better. The studio would have a microwave & extra sink, but the Contemp would have everything else in terms of the kitchenette area.
