No debate in my mind. I'd absolutely do it!
Different deal, but for various reasons I did a Disney After Hours night solo a few weeks ago (the late hours just didn't make sense for the rest of the family, especially on arrival day). I personally feel a little weird being in the park solo, but if I'm honest... it was a lot of fun! No worrying about if DW or the kids are happy... could go as slow or as fast as I wanted... could stop and just enjoy the atmosphere of the park. It was nice and care free!
I didn't arrive until 10pm (the event was 10-1am) so didn't use the 7pm-10pm time for that event, but I still felt like I got more than my $'s worth.
Anyway - a bit apples to oranges... but same general concept.
Plus you
need to do it for board research anyway.
