Sorry you were disappointed. Most restaurants ask you to check in 15 minutes before reservation. Being in a scooter (unable to transfer, and restaurants having prior knowkedge), we've waited as long as one hour past our ADR. Liberty Tree in Magic Kingdom and in Epcot for the princess breakfast. They needed to place me in an area that was "safe". We've always allowed 15 minutes prior to reservation time, and know that eventually we will be seated. A good idea is to plan 90 minutes to 2 hours for a sit down meal, possibly more with a larger party.
