My opinion, I hope Disney will give DVCr's first rite of refusal on another 50 year package. I will definitely encourage my son to do it. By then, I'll be in my 70's and would have already given it to him. (I can't wait til my son marries ~ we plan on paying for the honeymoon)!!!!
Or, Disney may convert all vacation homes into hotels!
However, I think the latter is not worthwhile! This has been a great money maker for Disney and the timeshare population.......
