We are going to GNP from Yellowstone & coming back through Mt. Rushmore on a 2 1/2 week roadtrip from Oklahoma. We have passports, but the kids passports will need to be renewed for travel in 2014. We will stay one night at Village Inn in Apgar and 3 nights at Swiftcurrent cabins. Is it worth it to take a day trip to Waterton? or just stay and enjoy our time around MG. We could stay one night at Waterton if needed, they have rooms available for us. At Many Glacier area, we will hike, but doubt we will take long hikes. Family of 5, kids will be 14, 13, 10 next summer. Google Maps shows it about 1 1/2 hour drive. Thought it might be cool for them to "visit" Canada.
