We styaed via Priceline bid (about $45/night) two years ago. Very clean, very much oriented to business and convention center travellers..
At the time ART was brand new and the staff were not very clear on how it worked and if multi day passes were available, they anted us to buy the ART passes each day and charge to room- I wanted to pay cash for them as room was already paid for.. they didn't like us very much after two days LOL..
The beds were just ok (Marriot across the street was better!).
Ask for upper level Disney view. You will have a wonderful view of DCA, Matterhorn and Castle. We were able to see a bit of the fireworks from our room (I think we were 7th floor - overlooking the pool?)
The rooftop pool and 4 (FOUR!!) hot tubs were wonderful! Pool is small but who cares when you can have a huge hot tub all to yourself each night!
They wash everything down each am and they have a small building with a staff person to give you towels .. can order drinks pool side (but they ignored us with our two boys running about the pool and helped only the single guy /business traveller).
They do have a breakfast buffet in the Oasis restaurant- it's not on the menu, it includes drinks that are on the buffet so don't order drinks from waiter and get charged extra to have them bring it to table.
The mini store and deli close very early in evening and open late in morning- not convenient for Disney guests.. If you need a bite to eat later at night, walk across to the Marriot which has a Pizza Hut in the lobby- they stay open past midnight and make fresh pizza for you while you wait.
Good place to stay for grownups but not very family/Disney friendly.
