Does anyone have experience with this? I've saved up to get a gift card for Hotels.com, but I want to make sure I do everything right. I don't want to make any mistakes and end up not getting my discount. I saved Tango cards and I can now purchase a $50.00 card to get a discount on a hotel room. I just don't see where I'm supposed to add the card. It may just be me. I'm a little .. overwhelmed with trip details right now, so I might have missed it. If you have experience, I'd love to hear about it. Thanks in advance for sharing.
