In my case, I rarely spend valuable (expensive!) park time eating. I like going in January and other times where the hours are often shortened, like in November when the party nights close MK early. If the park is open 9-6PM, I don’t want to spend time thinking about food, planning it, etc. If I’m hungry, I’ll just grab something and go.
If it was peak summer, and the hours were longer and I needed some breaks, I’d consider the QS plan where I could sit and enjoy a meal and watch the world go by. Or maybe even a plan with a TS meal in air conditioning once a day.
I’m going next week with a friend who has never been there, and we do have some meals planned for her visit- two character meals and probably a Biergarten meal- and even then the math for that is much less than any dining plan.
