I would love some travel advice regarding above trip. I am planning a winter holiday from Qld Australia to United states next Christmas. I will have New Year in Disneyland then on to have a look at Vegas. From there I have four days and three nights to get to Yellowstone National Park for the next booked leg of holiday. My husband and I have been to America a couple of times (love it) and are happy to drive. Could anyone advise me of good stopover places to see and stay. We also will be travelling with a teenage son so I hope you can send me some good advice.
