Hi everyone. I've started doing research for a snowmobile tour to Old Faithful. There will be two of us staying in Jackson for five nights this winter. There seem to be a bunch of snowmobile tour companies doing the same trip. Any thoughts on a company with a reputation of best equipment, guides, small group size and overall value? Do reservations need to be made now, or can we wait until we get to town and determine our ski schedule? Is the Old Faithful snowmobile tour the best winter Yellowstone excursion? We have both been on a machine before, but we're not avid riders. Thanks!
