Then option 3
Then option 3
A Disney Member Services member will pick up and ask for you member ID number so make sure you have it handy. They will ask your last 4 social security numbers, mother's maiden name (sometimes), confirm address and telephone number, and sometimes some other things too. Tell them the check-in date, check-out date, type of room, resort location and he/she will check availability. If there is availability then you just need to provide the names of who is staying in the room and ages of children (if any). If you have any requests like certain buildings, views, smoking/non, handi-capped, etc...then this is the time to tell them. Your written confirmation will arrive within 7-10 business days. That's basically it. Just FYI on the back of the membership card is the phone number to call. Oh...MS is open Monday thru Friday 9-5 with extended hours on Thursday till 7.
Hope this helped.
