I agree with the opinion that most people would feel fortunate to cash the check and be free of their timeshare.
It is not worth fighting. Only your lawyer will win, even if the lawsuit is lost, if lawyers get involved.
If you want to continue vacationing at Summer Bay, buy this 2 bedroom timeshare (or another one that better suits your usage dates, they are on EBay all the time) for $1 and pocket the other $699.
ANNUAL USAGE, 2 Bedrooms & 2 Bathrooms, Floating weeks 7-17, 24-34 & 51-52

The seller is paying all closing and transfer fees plus the 2015 maintenance fees. You would be getting a free vacation this year.
There are also some good deals on Summer Bay Resort weeks in the TUG marketplace, including $1 deals with prepaid maintenance fees for a free vacation. Just type "Summer Bay" in the Location filter:

You can't keep the week in building 104 because the building was condemned. You can replace that lost week with a week in a different building, if that is what you want to do, for much less than the $700 you received, and possibly receive a free vacation for your trouble. That seems more than fair to me.
