Usually, my sister and I share a 2BR and my parents stays in a 1BR. Sometimes we all stay together in the same resort. Last trip, my mom really wanted to stay at BLT, but didn't want to spend points for a 2BR at BLT so sister and I stayed at Copper Creek. It works for us as all of us sometimes like some alone time. We eat most of our meals together and tour the parks together for the bulk of the day so if my parents want to chill in their room away from us in the evenings, that's ok with us. We don't complain as we are not paying for a room so..... 
Thank you all for your input!! Our party consists of 3 couples. One couple has 3 boys ages will be 7,10,12 and 1 daughter 5. In addition there will be 3 single adult women. I own at Bay Lake and will have 900 points to work with. We plan on staying for a week.
What's the loft area at BLT? You mean the living room? A two bedroom will work for the group of nine. Family gets the two bedrooms (mom and dad in the master, kids in the second), adult women get the living room. Or mom and dad plus daughter in the master, three adult women in the second and three boys in the living room.Sorry, I vote for a BLT 2 bedroom...family of six gets one bedroom for the kids (too bad if they don’t want to sleep in the same room, are they paying), and their parents the loft area and use the kids bathroom if required at night, two of the single women get the other bedroom (their own beds) and someone gets the king...
