We stayed near the millers road pool last year.
It is very spread out, and the theme pool is not much to sneeze at. It is okay for a swim but not as jazzed up as some of the other pools - my daughter was tortured by the dolphin fountain because that looks like FUN and you can't go in there, the baby pool is a warm scuzzy little bird bath in the SHADE of the water slide, I didn't care for that. We live in Massachusetts and have much more fun kids splash and play areas around here, and we're not year round in these parts with the outdoor swimming! So I guess with OKW I was really really disappointed with Disney's lack of catering to it's youngest guests.
Go knowing that the rooms are a little outdated and it's spread out, expect 20 minutes to get out of the resort on the bus or back in to the resort on the bus (depending on which stop you are at - it's either going to take you a long time to get out, or a long time to get back), and you will be fine. I should note that we were there in late September, one of the least busy times of the year, and that was our bus experience, I bet it could be a lot longer with a lot more people getting on and off. We frequently got off at the first stop and walked the .75mi back to our room and beat the bus.
We didn't try any of the restaurants there so I can't speak to those.
We did like being able to walk to DTD - though make sure you know exactly how before you leave, we didn't have internet when there (didn't want to pay for it) so we got a little lost the first time.
And we loved the honeymooning river otter couple who spent a couple of afternoons on "our lawn".
And it's fun to be able to take the boat in to DTD from there, but it's also pretty slow, and popular so you might have to wait thru two boatloads or more if you go at a busier time.
We found the hot tub to be really uncomfortable at the miller road pool - because a couple young kids laid claim to it and were out there smoking and drinking every night, I think due to it's remote location, and there's no staff right on site to complain to there so it would have been a hassle to do anything about it - so we just went to bed early instead.
