Yup.
So far, DAK is listed as closing at 11:00PM every night starting May 27, 28, 29, 30 (Memorial Day Weekend,) and,continuing though the full month of June, and onto July 1 and 2.
We can pretty much "know" that July 3 and 4 will be late nights (maybe even to 12 midnight or beyond) and after that, expect the 11PM closings to be extended through the summer.
Just keep checking the calendars.
Have a great trip!
