I haven't done it. From general review I've seen I gather that the value isn't there for the cost. Negative comments I've seen include that it's not a "perfect" view of the fireworks, you still have to pay if fireworks are cancelled, seating and tables are inadequate and it's difficult to eat the snacks if you don't get a table. Positive comments I've seen have said that there's a character meet included (maybe more than one?) so that adds some value. I have seen mixed review of the snacks themselves, so that probably comes down to personal taste. Personally I would spend that money on one of the other experiences at DLR that get better reviews, like a dining package for Fantasmic or the WOC dessert party (on the off chance that they get it up and running before you go), or even just a regular TS dinner.
