If you do disney check packages first before you read what i'm about to post. Sometimes it is better and you can get more incentives however, there is a site I go to a lot for booking hotels, it's a bit confusing but take a look and see. I've saved up to 50% on some hotels when i've gone overseas and in the usa.
Priceline.com - name your price, is the feature I use, you name the star level from resorts to 1* your choice, and bid in the areas and what you'd pay for the hotel.
I regularly check out biddingfortravel.com or betterbidding.com to see what others have won to gauge an idea what I could get.
Prices are in US dollars keep in mind, which isn't too bad given our dollar is good.
Another site similar is hotwire.com but I've found they cost 15-20% more than priceline.
If that doesn't suit you, travelocity.ca has a guarantee if you find a lower rate on any site for hotel and air (like expedia.ca, aircanada.ca, etc) you can get the difference back, plus $50 voucher to use on your next trip and that's up to the day of check-in.
Best of luck!
