When you opt out of maid service when do you receive the gift card ?
Yes, when you opt out at Guest Services they email you an e-gift card approx a couple of hours later
What sort of things could you purchase with you e- gift card?
Yes you can. My advice is not to do it. For the $70 it is worth coming back after a long day to a clean room. It just revitalises you.
