K, this sounds wonderful and I do hope it works wonders for you and your business. I would like to think it would work for me but frankly I see it as another task to keep up with (for ME).
I also see it as another possible PITA causing problem. The more choices you give some one the more they have to decide - and if it is a couple they both have to agree. Wrong choice and they will be asking to change the sheets.
If I was charging what the W charges for selection of bedding, color scheme etc...I would do this without a second thought, cause I would also have the staff to help keep everything straight..
