Has anyone used "Travel the Rockies" for a trip to Yellowstone Park? This is a business that makes the reservations for the hotels/cabins etc and plans the exact itenerary for you. I am a little worried about this agency. I don't know anyone and can't find anything on them that is bad, but they want us to sent 50% deposit before we ever see any real evidence of a trip. I checks the BBB and nothing, but they've only been aware of them since april 2007. Please let me know what you suggest for checking them out, or if any of you have had an experience with them, let me know.
