We always got more, but if enough rides go down, that could make for some very limited selections. Also remember that during lightning many rides go down. Last summer we hopped to MK and the rest of the afternoon/evening was stormy. We lucked out, because we were able to get G+ for most of the rides that were open, Buzz, HM, IaSW, teacups?, Pooh, PotC, SM, LM, and we did CoP. Mostly though I was able to book back to back G+. The standby waits for the most of the rides that were open were all very long, like LM had- I think- a 60 minute wait.
We skipped: Philarmagic, carrousel, HoP, and Monsters, INC, could not get Pan, and I think we bailed on Pirates- though we had a G+ for it. I think we also skipped Tiki Room. Oh, we also skipped the Peoplemover, which was running, but it was a bit scary with the very loud/close lightning.
Rides that go down: BTMRR, Barnstormer, Dumbo, JC, Aladdin, 7D, Tiana's, Speedway, Tron, Astro, Riverboat, Treehouse, and TSI.
Much of AK also goes down during storms: all animal attractions, EE, Kali, Safari, and Triceratop Spin. That leaves: FoP (not G+), Dino, ITtbaB, and Na'vi. If one of those happens to be down, there would be only 2 G+ ride options. If someone booked Na'vi, then did ITtbaB while waiting for their Na'vi pass, with storms and Dino down, that could = just 1 ride G+ for the day if they can't hop. They could book the two indoor shows, but those are not rides.
