I'm thinking of doing the Fantasmic Dinner Package at Mama Melrose's... The main reason for doing it is to get the reserved seating
I would normally just get a counter service meal and be happy with that... I'll be MGM on the 3rd of September... Do I really need to do this to get a decent seat at Fantasmic, without waiting for hours?
were going the second week in Sept. and I think we'll take our chances and not do the dinner pkg. 
I've decided to hedge my bets and make an ADR... If WDW looks busy on our first couple of days then we'll use it (it is labor day weekend after all)... Otherwise I'll cancel it, 48 hours notice I think...
