iamdaisyduck, that's not always the case. While visiting in May, we tried to call and get a 5:00PM ressie for 4 adults and could not. So we went to Chef Mickeys at 4:30PM and checked in and was seated at 5:00 PM as a walkin....wow. In July we had a 5:00PM ressie, and while checking in, the CM announced to the huge line of folks that they could not accept NO WALKINS tonight. They were completely booked. So can you imagine taking a 5 year old and standing in line, only to be told to go away!!! how horrible and memorable is that? When we go as walkins we are usually just a part of adults--very little whining and kicking and screaming goes on if we can't get in (I've got that under control now). Just MHO. So I would imagine, during slower times, I would try for a walkin, busier times, I would think twice and also think how it would accept the folks in our party.
BTW: we've always had good service and good food at Chef Mickeys.
