At 7 months, most times of year you should be able to get lake view but likely not MK or standard view at BLT. For other times year -- such as Christmas week, December in general, other holidays -- often nothing at BLT unless you are looking for only a night or two. Moreover, you should assume with BLT that it will be very important to call exactly 7 months out and not wait beyond that because there will be a lot of members trying to switch into BLT at 7 months who also will be calling exactly 7 months out.
Personal View: I don't care much for the Contemporary look and area either and I would stick with AKV. In any event, the price difference should not factor in because BLT has lower dues per point than AKV and that is likely to continue into the future.
