Hi, Grace and Mickey,
I cannot answer the DVC question well enough, but we have rented points. The best place for info would be here:

Read the very first thread and then you could check out more threads.
DVC can also be reserved directly through Disney just like a resort room - you can call or find more info on
www.disneyworld.com It is more expensive that way.
Wish I could think of more options for 7 people - but a Family Suite would give two bathrooms, two TV's etc...I am thinking any arrangement with 2 bathrooms and 2 TV's would be a plus - be it a Family Suite or 2/3 rooms
Some guests rent a house/condo off site - many come with a pool! If you are renting a car and would not mind being off site that could be a possiblity. I found this on allears:
http://allears.net/acc/vhomes.htm You can read reviews there as well.
Did you check out the Family Suite thread I posted? Was that of any help?
Good luck!!
