Haha! Super exciting! I did the same thing a few days ago (...but for my mother's trip, not my own ) and I was as neurotic and excited as ever...even though it wasn't my trip!)
I was looking at my count down the other day and realized when we are in Disneyland next month we will need to make our WDW FP+ for our March trip. Sure is nice to have a sister with a DVC membership.
