I always break things down without a package to see whether it is a good deal or not. You did not say when you were traveling, so this is a little rough, but:
QS: $94/day=$500 w/tax
Tickets: $1,146 w/tax, $1,389 w/tax (park hopper)
Room: $89-$180/night plus tax depending on dates, so the room value w/tax is between $500-$1012.
All of this means you are getting you airfare for between $450 ($112.50/ea) and and getting it free while saving an additional $300. Run the numbers for yourself, but it looks pretty good to me.
