In particular:
1) Is having a car to move about in yellowstone give a huge advantage as compared to hoofing it? How did you get around the park when you went?
2) Does it make sense not to set up base in one of the lodges/hotels within the park, instead get a tent and camp outdoors? Whats r the pros and cons of camping during the entire trip?
3) Any other cost saving ideas and tips for enjoyin this park?
