If you believe what DRI's CEO, Cloobeck, said when he was the subject of 'Undercover Boss' TV show, he'll take back whatever you've got if you aren't satisfied. Carefully note that I'm not holding my breath.
I have a hunch, though if you just stop paying MFs, they will turn you over to collection.
If your 'dues' or MF isn't current, you can neither book into a resort, or give/sell/rent them to anyone else.
Best wishes.
