We went 31 October last year, which also happened to be our first night at WDW that trip. Needless to say we absolutely loved it, although DH was half dead by midnight and I ended up pretty much dragging him around the park...
In my opinion any date is a good one for this, you just can't go wrong. The atmosphere is absolutely amazing! The deco, the lighting... Oh, and we have no kids, so this is coming from the persective of just two thirtysomethings...
We are going for the first night too, 29 September. Ever the optimist, I figure if there's a hurricane and we miss it, we still have time to go on another date! Oh, that & the fact that I won't be able to wait any longer!
Me and my DH are 30 somethings too and have only been to the Universal Horror night which we love, we are going to go to MNSSHP this year - glad to hear from someone without kids that it's a good night for us too.
