We went last year at the end of September, first of October on a Mon., Tues, and Wed. We stayed onsite, and during the mornings, we usually used the regular line, and walked onto most rides. A couple of times, we requested FOTL and the attendant kinda looked at us like we were crazy. The lines at Popeyes moved so fast that we often were allowed to remain on the boat, or if they made us get off, just walked across the area where you put your shoes back on and joined the line. The only long lines I recall were at Ripshaw Rapids, but that was probably because they were having technical problems. It was a great perk, but not that necessary when we were there.
