I would start at the front of park . Gatekeeper and Raptor should be close to being walk on , Valravyn will have longest waits of the day , i would skip that and head to MF then Maverick . --- TTD , Gemini and Mean Streak do not open til 11am . if you have ERT privileges to get in at 9am you can literally ride all of these coasters (except the ones that open later) before 10am ! its a lot of walking early but worth it ! You will know if TTD is up and running from anywhere in the park , just look up !
