The bus from St. Paul Union Depot (which is the one stop for both Minneapolis and St. Paul, as the conductors announce on every trip I've been on ) is easy and relatively frequent. It's dropping from 15-minute frequency to 20-to-30 minute frequency from Union Depot on June 9, however (right now all buses end at Union Depot, but starting June 9 half of the buses will skip Union Depot and travel further east/north.) It's an easy trip, and even with the increased wait is still faster than doing the light rail.
