We love OKW because it feels like "home". We are at peace when we stay there.
The majority of our points are at OKW, with a small add on at BWV.
We enjoy BWV for our shorter stays. For us, it has more or a hotel feel, and offers some great dining options on the boardwalk and a great location for MGM and Epcot. The rooms are nice, but more compact.
When bringing guests along, OKW offers lots of space to spread out it. When you all retire for the night, it's hard to believe you even have guests with you! There is plenty of room to sit down and eat together, or just converse in the living room....also plenty of space when you just need to find a quiet corner for a few minutes of personal quiet time!
At OKW, everything sprawls around you, including your room! (we have no experience with studios, but we have stayed in 1 & 2 bedroom units) Everywhere you look there is something beautiful for the senses to enjoy! We enjoy watching the wild life, lots of rabbits, ducks etc. The golfers are entertaining too!
After busy days in the parks, there is nothing like coming "home" to OKW...once you drive into the resort, it is hard to imagine you were just sharing space with a few thousand people at a park. For us, it offers the ability to relax and enjoy our vacation. We will always call OKW "home"!
