If you don't like the terms, don't sign the contract. But just be aware that they are not going to change any of the standard contract terms for you. You have control over how many points you're buying, the length of your financing contract and whether or not you do direct debit for financing and/or maintenence fees. Otherwise all contracts for the same phase of the same resort will be identical.
I am curious, what provisions don't you agree with? I don't imagine that they would change any of the standard provisions like contract length (49 yrs), ROFR for Disney or other such stuff. But I don't imagine that you object to anythign like that. DVD needs to keep the contracts pretty much identical, give the number of member contracts it has.
Good luck!
