I am going to WDW on Dec. 4 - Dec. 14. My DVC home resort is SSR. Use year is December. I have a reservation in place for my home resort.

This will be my first time trying to change my resort at a 7 month point of SSR to another resort.

From what I understand, a good way to help me get what I want is to call day-by-day and change my reservation. Also, to NOT tell them I want DDP until the END of the day-by-day change because otherwise, they'd have to do more computer work on their side, plus it would take longer by phone and my chances would be slimmer (all advice given by intercotees and member services).

Questions:
1. Would I start on May 4th?
2. What time does Member Services open? I am on CST.
3. What are my chances in getting WL or BW?

Any other advice would be GREATLY appreciatd.
