It seems that alot of people request high floor, even number. There aren't enough villas for everyone to receive that view. Most villas that are lake view are on the inside of the "C", with odd numbers. We have had several different views at BLT - even number north (view of the MK), even number south (view of the marina), and odd number (view of Bay Lake and the BLT pool). Truth be told, the inner "C" villa was our least favorite. The 2 bedroom villas on the inner circle are smaller, and we found there to be alot of pool noise on that side of the building - so much so that our balconies were practically useless to us.
Will that stop us from staying at BLT again? Not at all, I just booked us another week in a 2 bedroom next June. I reserved lake view again, and will just take our chances that we are assigned an even numbered villa. If we get another odd numbered villa, it won't be the end of the world - we will still be within walking distance of the MK.
