We do, especially the MK ones. I love the 2am closing, although we do try and schedule something light for the next morning- resort morning, late entry into another park or a later breakfast. With the popularity of SDMT and A&E, the emh's at the MK are great for riding almost everything else!
My favorite thing to do is AK or MK in the morning, take an extended break in the afternoon. Then head to Epcot to use FP+, dinner and Illuminations then pop over to the MK just in time for EMH's to begin. It's a tiring day, but it's the best time ever!
