For clarity, if you’re staying on site and have park hoppers, you can book ILL for any park at 7am, up to 2 ILL per day. Off site has to wait for park to open.
You get to choose your time, so just pick an after 2pm time.
I’d probably check for test track just to get as early as possible, as I’m sure you’ll want to use before 2pm. If you have another person in your group, it might be best to have them try for the test track right at 7am. Also, if you get a higher number for Tron, you may want to look at buying that ILL for an early time just to ensure you can get on. Might want to check thrill data before you go to see what group #’s are typically called before 2pm
