Looking at what's available today as of opening, it's a rough day for Genie+.
At Epcot, Frozen and Remy LLs were gone before the 9 am regular opening, and Test Track was out to 8:20 pm. And Test Track is gone as of 9:15 am. That means at 11 am, most people will book Soarin' or Mission Space as their best choices, so even those may be gone by 1 pm.
At MK, Space, Jungle Cruise, Peter Pan and even Big Thunder were all out to mid-late afternoon by 9 am. HS is also looking like everyone will get two big rides and that's it, unless they use an LL in the morning to re-book more quickly.
During super high crowd times like today, are ILLs a better value than Genie+, other than maybe at MK?
