Retired couple using Banff and Jasper as base for driving trip through Rockies in June. Staying at local BB in both cities so need recommendation on places to purchase picnic lunches for day trips. Another question, different subject.........if our time allows we plan to visit Glacier National Park in Montana. Probably will need to spend the night there. Anyone have recommendations for a place to stay? Are the Red Bus tours there worth it or will a self drive be just as well? Thank you.
