We had a 4:10 ADR for the FDP at H&V in August and asked that morning at the restaurant hostess stand if we could come a little later. We knew we wouldn't be too hungry at that time having a 12:00 lunch. They told us to come between 4:30 and 4:45 and it worked out great. By the time we finished, we saw the parade, went on one ride and headed to Fantasmic (based on advice from our server to get there up to an hour early). We thought it would be packed, but we were one of the first families seated in the reserved area. My husband and older son left and went on a couple more rides while I saved our seats. When they got back a half hour later, there were still plenty of seats available around us.
