How much time to plan for Bow Summit and Peyto Lake
 

When driving Icefields Parkway, how much time to devote to Bow Summit and Peyto Lake, then how much time for Parker's Ridge. If driving to Jasper, where is a good stopping place for picnic lunch? We have a full day to spend on Parkway. We won't have much time on our return trip back to Banff as we have a tour that day until 2pm. We will spend two nights in Jasper.
