We receive the $75 gift shop gift certificate for being at the passionate love level in the Romance Rewards program. At CN in April 2008 and March 2009 and at CSA in July 2008, we purchased items like sunblock, shampoo & conditioner, etc., by charging them to our room and "paying" for them at check-out by presenting the gift certificate. At CSS in August 2009, however, we were told that we couldn't charge items to our room and pay for them with the gift certificate at check-out. We had to use the gift certificate at the time of purchase and were required to spend the entire $75 at that time.
I don't know if CSS simply handles gift certificates in a different manner than do CN and CSA or if a new chain-wide policy has been implemented. Hopefully, it's the former.
I know everything, and I'm always right (just ask my husband).
I think CSS just does things differently. We had to spend it all right then and there, too, as CSS in October. Last December, at CSA, we billed it to the room and presented our certificate on check-out to basically zero out the charge.
We were just at CSS last week. I think they finally figured out how to handle the vouchers. We presented our voucher when we first went to the gift shop. They kept the voucher (with your room number written on the back) and they would staple your receipt on the voucher each time you purchased something. Each time you returned to the gift shop, you would just tell them you have a voucher and your room number, and they would keep track of all your purchases and let you know when you reached your balance. No problem mon!
