Please note that there are TWO REVISIONS of the floor plan, so please, do not get in confuse.
The reason for that is adding fun room, lately.
My suggestions would be that you use revision without fun room, later, when kids grow up, just my 2cc.
Also, please note that fire place, in master bedroom is kept, so I am pretty shore it will be used for good purpose.
In the living you also have one fireplace, with TV set above it.
The pool is shifted back for about 7 foots, to lake.
The hot tub is located, on the right side of the fire sitting place, you'll see different shade of pool wataer.
Fire sitting place, is obviously the bridge-like structure just infront of the house.
