Some FAQs about cashless at the Gaylord National

The resort accepts all major credit cards including its restaurants and spa. Debit Cards are also accepted throughout the resort; however, upon room check-in at the front desk, the guest’s bank will place a hold on the debit card for room & tax plus $50 per day for incidentals. This hold will not be released for up to 5-7 business days after checkout. We recommend using a credit card at check-in to prevent this hold on the guest’s cash funds.

There is a Cash-To-Card kiosk located on the lobby level, by the main entrance next to the celebrity service office. This machine issues a Mastercard ranging from as low as $20 to a maximum of $500. There is no fee to use the machine, and if the full amount on the card is not used at the resort, it can be used anyplace a Mastercard is accepted. Cards are not returnable or exchangeable for cash.

The Cash-to-card kiosk also has a bill breaking feature which can be used free of charge.

On the back of the issued card, there is a website and phone number. The site will allow guests to check their gift card balance, review transactions and track refunds.

The hotel can issue a check for any needed refund.
