We have been waitlisted twice to move from late to early seating. Both times we tried to change our seating, which is now done at the same time/location as Palo reservations. In both cases we were unsuccessful. The first time, we gave up then and had second seating. This last time, we went to our first dinner at second seating and talked to the Head Server. He was able to get us switched by meals end. However, we were having such a good time with our table mates we decided to stay with second. We, however, weren't dealing with small children. Bottom line - if you really want to change and don't get reassigned before your first dinner, don't give up- ask the Head Server.
