How about well-worn shoes.
I've wondered how far I walk during a DL visit. What are your distances/hours?
DL let's you bring food in now. In the 90s I heard they didn't.
I'm an ultra health enthusiast(75% raw, 60% fruit, 100% plants), and goin' to DL doesn't stop me.

I go through a lot, bringing my own food. But it saves money AND time with resturants. I find I'm at my best with just fruit and veggies. I could live off the fruit carts but it'd get expensive. So for my latest 3 day trip, I brought most of what I ate from home - a suitcase and backpack filled with 20 lbs of produce + sunflower seeds, not much cloths, or whatever regular people bring
DL went great. Had energy the whole 15 hours...got in 23 rides.
