Since you have a special place in your heart, and you enjoy studios, why not hang on to your DVC for a couple of years and use half-ish of your points for a studio stay and rent the other half. Or -- rent them all. You don't necessarily need to rent on the open market. I help a close friend rent her points to business associates of ours, and have had no problem renting out the past 3 years of points to trustworthy people who have the $$ to go. Perhaps you know some people like that who you could rent to. That would give you a couple of years to really experience the changes that you think you won't like (MB's, FP+, etc). Who knows . . . you may end up liking them. I have not yet experienced these changes, but I am intrigued by having FP+ for evening hours at the parks; we have never ridden TOT in the dark!
You could easily cover you MF's if you rent out half of your points. If you rent them all, you could cover almost two years of MF's. Renting for a couple of years might give you some proceeds to pay down the loan (if you have one). Granted, if you wait two years, your AKV points may be worth less (possibly a lot less). But, with AKV selling out soon, I have a feeling AKV resale will stay close to the current level for a few years, as newer owners find out that they want more points, but "can't get them anymore" from Disney. Who knows . . . I am not an economist, real estate expert, or financial planner, so it's just a notion.
If you did buy direct from Disney within the past 4-5 years, hopefully it is paid off. You probably paid in the upper $90's to low $100's, but at this point you stand lose $30-40 per point in this sale. Additionally, the broker will get 10% of the proceeds. If you still have a loan, you could be "upside down". Keep that in mind. Also, if you have already used your 2013 points, or even some (or all) of the 2014 points, your contract is going to sit on the market for quite some time.
With regards to passing DVC on to your child, I think you are finding out why you would not want to strap some young person with the challenges of owning a TS. I am saying this so others who are considering that possibility understand the consequence to their children of passing on the "Magic". But, looking at your signature, your DD is approaching graduation, so perhaps hanging on and renting for awhile would give you the chance to give her an awesome graduation trip with friends. Just a thought.
I am sure this is not an easy decision for you. If you do sell, good luck getting a good price!
