I think when we are doing a studio we will do an extra towel set and a extra T & T for $16 that will cover us for the entire stay of 5 days.
We did a 2bdrm on our first trip home and it was nice to have the W&D right there but I really don't see us doing the poolside washings.
We also liked not having someone in our room each day as well gave us the real home feel.
