We stayed at Hilton last yr with a Priceline bid of $40.
I agree it is geared towards the business traveler not for families. The cafes in the hotel closed early and opened late so many times we had to leave the hotel to find something to eat after park closing. (Hop across the street to the Marriot- they have a Pizza Hut )
The boys could care less about the pool but we did enjoy the FOUR hot tubs! Very nice to relax in after a long day at the park and had one to ourselves most nights.
We walked but took the ART back at park closing. (The staff were not very helpful about how the ART system works. They kept insisting on charging our ART passes to the room and we demanded to pay for them in cash. They also would only give us daily passes and I know there are mulit day ones) We never tried it but, you could walk a block over and use the trams from the parking structure to the main entrance.
We found the beds to be not very firm .. they kind of swayed as we got in- so we shoved the mattress and box up to the wall to support it which helped.
My suggestion is to ask for an upper floor with Disney view. We had a great view of DCA and could see part of the fireworks from our room. It was fun to wake up in the morning and watch the park starting its day.

Walk up the street (cross Harbor) and check out the fruit/vegetable stand. We bought fresh fruits and nuts for snacks. It was also a learning opportunity on strawberry farming and a chance to see hardworking farm workers in the early morning (DH parents were migrant farm workers when he was little)
Get the breakfast buffet at the Oasis -it's not on the menu but it was reasonable compared to the regular offerings.
