Initially we had cabins booked over in Idaho. These were bare bones rustic cabins (ie. a hut) but they were supposedly heated. When we had to abandon Idaho because of snow I did throw my tent on the bike as I hit the road with no reservations. Not everyone had tents though and accomodation wasn’t hard to find so we roughed it in a Motel 6. Personally I would have preferred to camp. Would have been fine sleeping I’m sure but hanging out before then might have been cold.
You are going to love BC. I need to head up that way on my bike once the mountains start to thaw out. Unfortunately in June I’m scheduled to be riding from NC back to WA, but if timing works out I would take a weekend trip up there to meet up with you.
