First, I want to say thanks to everyone on this thread. It has been invaluable as we prepare for our family's first trip to WDW.

We're staying at CSR (which we chose because of all of the awesome pics on this thread!) in August (18 days to go!) but I had a few questions...
1. We have reservations at Cali Grill to watch the MK fireworks the first night we're there. I'm not worried about getting from CSR (we will have no car, relying on Disney transportation the whole time) to CR for our reservation, but I'm wondering what is the best way to get back to CSR after the fireworks? I thought about a taxi cab but then was concerned about the hordes of cars leaving MK as it closes.
2. We have a 7:40 a.m. ADR at Ohana for a character breakfast one morning. How early do the buses leave for the parks and what's the best way to get to Poly?
Thanks in advance for the help, you DISers are fantastic.
