First congrats for buying your
DVC! OKW is a wonderful resort and fully mature in landscaping.
A good deal is what you think a good deal is? But all in all, yes for the price on a fully loaded contract it is smokin deal! However you will then have to pass ROFR and Disney may pick up your contract. I think the average price for OKW right now is around $77 per point. Someone please correct me if I am wrong.
As for is it safe? I bought resale from TSS and was more than happy. Not only did I get what I thought was a good deal, when you buy from a Disney owner you are also helping them out. No one really wants to sell a DVC but during hard times it is nice to know that you purchased from a person who also loves Disney and needs the $.
The points that exist are good for the UY. Ask your seller what that is. If is say July then your point are all good until next July, if it is April then they are good till April of 08. Make sure you know this and either use them or bank as much as you can.
Banking is an entirely other subject with rules with timetables etc. But you can bank the entire amount, then 75% of your total points, then 50% of your total points, etc down to you loose your points if they are not used up. Banking is important!
As far as a con? The biggest thing in my mind is that OKW will be the first to end the contract so it does not have a long contract life. For me, I will either dead or most likely unable to go to Disney. In that case I will leave it to DS.
I hope this has helped. I am new to our DVC and their are members with better answers to your questions.
Good luck, April
