This is one the reasons HS is so frustrating right now. With young kids (no ToT or RNRC), we did all of TSL at RD (with SDD FP) and did a few other minor things and had nothing to do by like 9:30 while we waited for our Jedi Training time and RotR. We decided to go back to the hotel to rest and return at noon once the shows started. I’ve seen a few people say they book a late breakfast around 9:30-10:00 before the shows start. That might be a good strategy.
