I personally love this idea! Finally, people can be held accountable for reservations and not waste the restaurants' time and money. People don't understand that when restaurants believe many patrons are dining a specific night, they hire more people in the long-run...what does that do? The cost of dining at Disney skyrockets for EVERYONE, especially like it has in the last few years.
they already do it at Akershus. I was so surprised when they asked for my credit card to hold. But I could see why they would have to at super popular restaurants!
