I hadn’t looked at Rivers of light times since they extended park hours last week. Looks like it is now 8:30 and 9:30. I think you could definitely try to do the earlier show then hit FOP as long as you don’t mind a late night. I’ve heard reports here of people getting in line close to closing time and only having a 40 min wait despite the listed time being 2 hrs or something crazy. Obviously Easter week will have high crowds but that might be preferable to the crazy crowd at rope drop. I see you got to AK in May very early so that might be another option if you don’t want a late night.
