First of all if you are going to be spending a lot of time away from the parks/in your room I would definately splurge on the one bedroom at either resort.
If you will be inviting family to your room, the one bedroom at OKW cannot be beat. Is is hands down the most spacious of all DVC resorts. The living room has a chair, loveseat, sofa, table with 4 chairs and a huge deck. We loved it.
In our opinion, the beauty of the WL lobby and grounds are unsurpassed at Disney, but the rooms are smaller and require more points.
Also, due to the size of the resorts, the one bedroom at OKW may be easire to obtain.
If you want a light and airy decor, go with OKW.
If you like a dark and rustic decor that makes you feel like your are away from it all, go with the WL.
One last note: the rooms at OKW tend to be quieter because you have your own outside entrance. (No noise fromt the hallways.)
I'm sure you will be extremely happy with either resort.
Let me know if you have any other questions.
