Yes, location lol. Just because it is closer on a map doesn't mean it's a better location when you can't get anywhere as easily...
OKW is walkable to 0 parks, monorail to 0 parks, boat rides to 0 parks, skyliner to 0 parks, and busses to all parks, which is typically thought of as the worst transportation mode
Our first two 'on property' stays were at OKW. First time we used bus transportation only and it wasn't great, so next time we rented a car and drove to all the parks. Well, we didn't love that either. For our latest visit we went to the Dolphin because we love the EPCOT area. Well, let me tell you, you cannot go back to staying at OKW after tasting the ease of transportation and amazing atmosphere around Crescent Lake. So we decided to bite the bullet and buy BWV!I do want space and location, which is why I settled on Boardwalk for my home resort.
I know we could've paid much less by buying OKW, but truth is, for us, all the other expenses of a Disney trip (tickets, meals, etc.) are far greater than the accommodation expense. So if we're going to dump thousands of $$ on a Disney trip, I'd rather invest a little more on a good location.
