I would make a reservation at OKW or where ever you can, then get on a wait list for BWV if that is where you really want to go. I have had std view 'luck' at less than 7 months, 2 times, both for summer months, which are NOT super high demand times. Once I got the room while on the phone, the other time was a wait list that came through in about 6 weeks. With a reservation at OKW or ??? at least you have a place to stay if the wait list doesn't happen. Good luck, and have a great trip.
CONGRATULATIONS and WELCOME HOME!!!
