For context, my friends and I are heading to Banff for May 9-13th. We're hoping to go to Lake Louise on the 11th, but we're really confused by this whole shuttle/parking situation. Do we need to book a shuttle, are we ok to just drive there? Thanks in advance!

P.S. Any thoughts/knowledge on what lakes will be melted/melting during that time?
