Unlimited Disney Quest is part of the FITS passes, as well as the two water parks and downtown Disney. My tickets came with a voucher for a free character breakfast as well, which was a choice of 4-6 diff. breakfasts (not Princess ones) including Chef Mickey's Ohana's, etc.
The best thing about these passes is that you have unlimited access to DQ and the water parks (as well as the 4 Disney parks, which most passes have anyway) for the 30 day period after activation. This way you could actually head to the water parks every afternoon during the hottest part of the day, and not worry about using up the Plus options that most passes have a limited # of.
We're going to Disney for 9 full days, so these passes made the most sense for us. They cost less than the 7hopper+4 plusses passes we could have purchased through the military, and give more options (7-day hoppers don't include DQ as a choice in the plus features at all, which is $33 at the gate).
