We are surprising our sons and staying at Nickhotel the last night of our trip--couldn't afford the whole week and got a sweet timeshare deal at Marriott Grande Vista.
When I called to make the character breakfast reservations, they checked my room reservation number before allowing me to make the breakfast reservation. They also take a credit card number, similar to Cindy's.
It sounds like this is pretty popular, so they are keeping it to hotel patrons.
