You have a fridge and microwave so bring your own food or go to the grocery store. No way to do that? Then just pack some sardines or other similar portable non-perishable food in your luggage. Can't do that? Then eat the hotel swill and go back to real food when you get home.
Years ago I worked at Sea World in San Diego. I have to tell you that theme park food is the absolute worst quality food and worst tasting food there is. If you can avoid eating it, do.
