I've always said "ADR's are not needed, just call the day that you want to go". But, I got a little worried, I wanted to have dinner during Illuminations at the R&C later this month. So I called expecting to have trouble getting the ADR, but there was no problem. I was looking for a table for 4 for 7:40 pm during the week of May 21, and I had my choice of days. So, for all of the non-compulsive planners out there, you won't go home hungry.
