Since you say 'we', I'm guessing there are 2 parents or other adults that will be there? When mine were little, DH and I had the double stroller on the bus routine down to a science. First, I always would bring an empty shopping bag and line the bottom of the basket with it (think grocery store 99 cent bag)...When getting near the bus entrance, I would grab all 'junk' that accumulates under the stroller (have drunk water bottles, dirty shirts that were changed, souveniers, empty popcorn bucket) and throw it all into the shopping bag, diaper bag would be on dh's back. I would hook the shopping bag through and arm and grab a hand of each kid. DH would either enter via the back bus entrance (if open) or walk there immediately and stand near that back entrance with the stroller leaned up against the pole. I would sit with a kid on my lap and one next to me. DH would be the first one off the bus and set the stroller up on the sidewalk and I could walk out and usually put a sleeping child right down.
