Going to cedar point and I am on a diet, help!!?

I'm on weight watchers and going to cedar point this weekend with my friend and for breakfast lunch and dinner we are eating at a restaurant and eating at the park. Problem: I never see anything healthy or low calorie sold at amusement parks and same with restaurants, they're usually not 'diet friendly'. I already used all me flex points for this week and don't know what to do or expect. Any advice? Please help!! And if you know anything that they sell at stands there that is low calorie, like under 400 calories and not deep fried or anything(I like healthy options) please tell! There are probably salads but I would really like other options. Thank you!!!! Appreciate your time to answer.
