Unfortunately, we will only have 2 nights to spend at these hotels.
We are leaning toward staying 1 night at each hotel because we have heard great things about each, and have activities we want to do close to each one (whitewater rafting near LL, and the springs near Banff). We also considered the amount of time it takes for checking in/out, packing/unpacking, parking, etc, but we are pretty 'efficient' travelers so we don't think the time lost will be very significant. I'll update with our room info once we make our reservations. Thanks for everyone's input!
