Hi Julann!
Thank you for visiting the Moms Panel again, and thank you for your kind words. Always happy to help!
I am assuming you are talking about the car rental companies on-property at Walt Disney World? There are Alamo and National car rentals based at the Walt Disney World Car Care Center located near the Magic Kingdom. These both provide shuttles that will pick you up from your Disney Resort Hotel and take you to the Car Center to pick up your car. There is some useful information about this on the www.allears.net website, under Planning, Transportation, Renting A Car.
At Value Resorts you will need to take your own bath towels from your room to use at the pool. When you do this, you should request clean towels for your room from Housekeeping.
All character dining is available on the 2012 Disney Dining Plan and the 2012 Disney Deluxe Dining Plan. They all require one Table-Service meal, with the exception of Cinderella's Royal Table which requires two Table-Service meals.
Full dining plan details are here.
I hope I have answered all your questions, please come back if there is anything else I can help you with.
