If you buy at HH, you will pay a prorated portion of 2002 dues. For example, if you sign the papers on June 1, you will pay 7/12 of the annual dues. Even if you take advanatage of the MB program and sell back your 2002 points to Disney, you will still pay the proprated protion of the 2002 annual dues.
In 2003, you will pay the total amount. You can either pay the dues as a lump sum sometime in January, 2003 or you can elect to pay them on a monthly basis. In that case, you would pay 1/12 of the annual amount each month. You can only pay monthly if you allow Disney to take the payment directly from your checking account.
BCV works a little differently this year only, because the resort doesn't open until July 1. If you have a use year before July, you pay a total of 6/12 of the annual dues. (You can pay this as a lump sum or elect to pay monthly). If your use year is later, you pay the prorated portion that begins with your use year. For example, if your use year is December, you would pay 1/12 of the annual amount. Again, you have to pay the prorated portion of your maintenance/annual dues even if you sell back your first year's allotment of points.
