(FYI, I'm commenting as an owner at BLT, so take that into consideration as you read this)
IMHO, DVC made two serious mistakes with BLT....
First, they designated too many points for the building. Second, either as a result of #1 or to compound it, they developed three point categories.
The problem with #2 above, is that there are a handful of MK views that are basically glorified Std views. There are also plenty of Lake views (as evidenced by the OP) that are, well, glorified Std views. As a result, you've got a handful of preferred level views (in the lake and theme park category) that are really disappointing to the vacationer. I've stayed at BLT two times since we've purchased, and I have to say, I've argued with the front desk at the contemporary each and every time, after being presented with awful rooms.
The problem, unfortunately, isn't as simple as moving all of the bad-view rooms from MK/lake view down to Std and calling it a day. If you do that, (and this is where problem #1 above comes into play) you need to re-allocate the difference in those mk/lake view points into the Std view....which would raise the point cost for std views to something that would be untenable for most DVC owners at BLT.
Had DVC had a more modest point total for the building and launched with 2 point categories, preferred and standard...where preferred has the best views to offer on either side of the building and Std made up the remainder of the rooms in the building....alot of these problems would be nonexistent. Moreover, I suspect BLT would have sold out 1-2 years ago with relative ease.
Regardless, my favorite category is lake view. Standard is such a small block of rooms..and you're virtually guaranteed a view of a dumpster or something equally undesirable. MK view isn't all that it's cracked up to be, given your access to the TOTW lounge. The other benefit of lake view is that since there's such a large percentage of the building in this category, if you get to the contemporary and find your room offering sucks...if you make enough of an uncomfortable squealing noise in the contemporary lobby, the cast members will generally try to find you a new room.
