A way to get poor, unsuspecting suckers to buy an overpriced meal at a bad restaurant just to have a reserved seat stuck off to the side in a giant amphitheater where people who didn't buy the package get better seats.
Ok, so the above is (maybe) a little harsh. It just isn't for us. Having done it twice, we will never do so again. At least not until DHS gets a better restaurant (not gonna watse 2TS on Brown Derby, which would be a 1TS in any other park).
If you go during a very busy time of year it may be worth the package. For slower times I'd just get in line early enough to get a spot and eat where and whenever you want.
