I did a copy from the Disney Club webpage that shows the information about this, here it is:
----------------------------------------------------------------------
To take advantage of this offer, call (800) 951-2657 or your
travel agent to book a
Disney Cruise Line® vacation. Please ask for booking code "DC" to take advantage of this special Disney Club offer and provide membership number.
Offer valid with initial booking on most sail dates commencing 4/1/02 - 11/21/02 and 11/30/02 - 12/19/02. Other discounts do not apply. The onboard credit is per stateroom for each stateroom occupied by an adult Disney Club member. Credit good toward merchandise, spa treatments, shore excursions and other onboard activities. Any unused portions are non-refundable and non-transferable. Prices, savings offers, sailing dates and other terms subject to availability and may change without notice. Be sure to ask for offer code "DC" and provide membership number.
--------------------------------------------------------------------------
I can't see how it can be restrticted by location of residence.
The address that I have for an email contact for
DCL is:
dcl.guest.communications@disney.com.
Just a suggestion, if you're working with a travel agent like
Dreams Unlimited, they could easily find the final answer for you, which would be easier because of your distance and inability to access US 800 numbers.
hope that helps
