We stayed there for 10 nights back in 2014 in a two bedroom villa, we took the in-laws with us and as much as I love them, there was no way we were sharing a room with them for 10 nights.
We were looking at booking two rooms at the Yacht Club & asked the Disney Rep from Disney UK to price up OKW at the same time.
I can't remember exactly what we paid but compared to what the YC would have cost, it was several thousand UK pounds cheaper, they were offering a significant discount at that time for OKW & SS, free dining & memory maker were included & they were also also doing the 14 day ticket for the price of 7 offer as well.
Just looked at the OKW map to remind me which building we stayed in & it was 48, so a fair distance away from Hospitality House but still within walking distance if you felt like the exercise, this really did not cause us any issues with buses or pool use as the stop that we used was never busy so we always got on the first bus that arrived, there was also a quiet pool just across the road.
The in-laws had dinner in Olivia's one evening & really enjoyed it, they still talk about it even now.
All four of us fell in love with the resort & in particular the space that we had in the villa, not being close to a park did not cause us any issues, any time that we wanted to be somewhere quickly or didn't want to wait for a bus we drove, the boat ride to Disney Springs is great as well.
The resort itself is beautiful, it still has that Disney magic & special things that they do so well but it's not over done & it really is a relaxing place to stay.
We tagged on 4 nights at the YC at the end of our stay & stayed there again in 2017 & are booked there again for 14 nights in November, as you said there is something special about being able to walk to Epcot or HS from the Boardwalk area, but we would definitely go back to OKW again if we were taking the in-laws or other family members.
