Hi Jeffrey!
Thank you for visiting the Moms Panel!
According to the Calendars for the water parks -
Disney's Blizzard Beach is open in November 2012, from 10.00am-5.00pm each day.
Disney's Typhoon Lagoon, however, is showing as being closed during November for refurbishment. I would recommend you check the Typhoon Lagoon
calendar nearer the time of your visit to see if anything changes.
You can absolutely drive your own car from theme park to theme park during your visit - if you buy a parking ticket for a theme park, this will be valid for the whole day at any theme park - so you only pay the parking fee once per day. If you are staying at a Walt Disney World Resort hotel, you do not pay for parking at the theme parks.
If you have any other questions, please come back and ask me - I would be happy to help you plan your magical vacation!
