Well, what my husband and BIL did was take my nephew's stroller with them to throw it in, so they didn't have to carry it the whole way(I know it sounds bad...

) Then I think they asked for bags maybe at the gas station, but when they got back on the bus they were surprised b/c everyone was asking where they got it from. The other people on the bus were all impressed/jealous that they had figured a place to get it.. LOL I would have felt awkward as well, though, so I can understand that... But it is definitely an option for you..
