Hey Jackie, where are you going to be staying?  We stayed at the Grizzly RV Park in West Yellowstone last year.  It was really nice, but you do have to pay for wifi.  They have a dog walking area and there are dispensers with doggy poop bags all thru the park.  The spots were plenty wide enough and the people at the office were really helpful.  Downtown, there is a nice restaurant - I can&#39;t remember the name of it, something to do with trains.  They have a few train cars inside that are refurbished to reflect their original state way back in the early 1900&#39;s.  You can walk thru the cars.  There is also a BBQ place there that is really good.
