For mid range I can't recommend the Newport Bay enough, but pay the extra for an Admiral's Floor room. It is a big hotel and I can see how some rooms might be an awfully long walk from reception/lifts etc., but we (4 adults, 3 kids) thoroughly enjoyed it.
As 2 families we were given 2 superb rooms not far from the lifts with lovely views out over the lake. We got to have breakfast in a very exclusive breakfast area the Captain's Quarters by invitation (for staying on the Admiral's floor) so no trouble with breakfast queues. Have a look at my trip report for any more info.
The only thing I would say is be aware that the NPB has a large conference facilities, there were several conferences on whilst we there, so what I found unusual was men and women milling around the hotel in business suits during the day and evening wear at night. I had quite an odd experience when I found myself in a lift with 3 other women, whilst they were in elegant evening gowns, I on the other hand still had on my Mickey Mouse Anorak and Minnie Mouse hat with ears.
DH loved the consierge service, I loved the hotel, full stop and the boys loved the nautical theming. I wouldn't hesitate to go back, although it's my intention to try and stay in all the Disney hotels so have been thinking about the Sequoia Lodge or New York for next time.
BTW it's a lovely walk to and from the NPB especially at night, I love the atmosphere of the village, and the lake is so beautiful at night as is the NPB, it's beautifully lit up.
