Wow, I had missed this. This is a surprisingly good idea, and actually the location makes it relatively on-theme even. Seeing a food truck parked outside of Enchanted Tales with Belle wouldn't work, but in the Studios, it works.
They will continue to operate at DTD at night- They will be at Studios for just lunch then back to DTD for their regular hours
The trucks are very mobile- Ive seen the MK one parked in 4 different locations at DTD as well as driving down the road a few times
I think my only complaint with them is the price point- Its all about 3-5 bucks more than I am willing to pay for 'truck food'
I can see it being a big 'win' overall- Events at Wide World? Send the trucks, Large Conventions at resorts? Send the trucks, RunDisney races? Send the trucks
