I was at SFMM last Monday, and although it was not a holiday, the weather was kinda iffy. We got there at 10:30, and considered ourselves "done" by 5. There were some closed rides: Deja Vu, Ninja, Gold Rusher. One side each were open on Superman and Colossus.
I never saw more than a 4 train wait for X except for front row. Almost everything else was very close to a walkon, except Riddler's Revenge, which was easily the longest wait of the day at about 6 or 7 trains. No, I take that back. The longest wait of the day was trying to buy lunch
