Just thought I'd throw this out there - I bought the Orlando Entertainment book ($22 including shipping) and they had a coupon in there to book through Hotels.com with a 10% discount. Hotels.com had the same price for Port Orleans Riverside as booking direct with Disney and the other on line sources I found so we ended up getting the hotel for $149.xx vs $166 per night as listed as the current Disney special. More than paid for the book with this one discount alone.
The only downside is that they charge your CC right away for the entire stay - so be careful with this but they do allow you to cancel without fees up to a certain point which helps.
This is our first time staying on Disney property so I'm hoping this is a nice hotel - seems like people have had a good experience there.
It appears there are lots of discounts for local restaurants and mini-golf which we use a lot along with other national discounts.
Just wanted to pass it along as I haven't come across any other discounts off the on site Hotels.
We are staying the next 4 nights at Emerald Isle so we're hoping the book with save us $$ for local restaurants, etc..
Hope this helps - didn't even know this discount was in the book until I recieved it..
