I'm not sure friday makes a lot of sense for a couple of reasons. First off it's at 8 which leaves only 2 hours for DATW, definitely not enough time. The PI meet is that nite and that means people have to get from Epcot to PI, driving is a bad idea. Karaoke is traditional after DATW and that works on thursday. I do agree that it is always traditional on fridays but the illuminations thing makes that pretty impossible.
