I don't know how old everyone in your group is, but right after the fireworks is also a great time. We were there two days after Christmas (so it was quite busy). We watched Wishes from behind the Castle and realized that the entrance to PFH is in the area that is closed during the fireworks as a debris area. After the fireworks we waited for the area to re-open and the line to re-open. We were one of the first groups in line behind the people that were still waiting from prior to the fireworks. We waited about 45 minutes, which was much better than the 120+ that it had been throughout the day. We were all adults though, so time wasn't really an issue. The poor little girl,in line behind us was sound asleep by the time she got meet Elsa!
