One of the problems with Disneyland compared to WDW is that there are many more locals who attend compared to at WDW. Pre-covid, I heard at DL it was 70% locals to 30% tourists on average and the opposite at WDW. Regardless, if you live nearby, you can sit on a bench or wherever for a couple of hours if the parade and maybe some snacks is all you are planning on doing for the evening. If you are there for just a few days, you want to get as much in as you can.
