I think you'll be fine scheduling the fp+ earlier in the day anyway. Again, Pandora wasn't a factor, but at the end of the night with an 8:30 close, almost everything else was walk-on. We did two in a row on Kali after dark (fun!) and waited one cycle for Everest (also fun in the dark!). Dinosaur was closed for refurb, but everything else over there was walk-on as well.
