For lunch, I recommend Festhaus- it has a lot of options (pizza, mac 'n cheese, burgers, even Chinese food) and the LaRosa's pizza is amazing. For ride recommendations, try to ride all the big coasters (Vortex, Beast, Diamondback, Racer, etc.) plus Drop Tower and, if it's warm enough, any of the water rides. As others have said, if you do want to ride Firehawk, make sure to get there first thing as the line moves pretty slow. Also, lockers for loose articles are $2 (I think they are still $2?) at Firehawk's entrance (there are lockers at other rides, but this is especially important as Firehawk is a flying coaster that will turn you upside-down while you are laying down!) Finally, have fun and thanks for visiting Kings Island!
