They'll put them in to go boxes for you yes. We've done this at Boardwalk Bakery, Pop, CSR, POFQ, and PORS. If you want to use up some meal credits at DTD, WGP Express and Earl Of Sandwich will also pack things to go.
Yes, you can get your meal to go from any resort QS. I have had different experience with how they pack them from resort to resort. Some use a paper plate with a plastic dome over it. This is bulky and they do not stay shut very well. I have noticed some deluxe's serve their meals in boxes (instead of plates) That is very convenient.
Thanks for the replies! We will have QS credits and our plane leaves at 5, but DME probably will pick us up too soon after we eat our last meal, so I thought if they offer meals To Go, we can use our final credits for To Go meals.
I was in Vegas recently and the hotel offered box lunches To Go for the airport, and I thought that would be perfect for our last credits at WDW! I guess it's the same thing if we just take our meals To Go!
