This is one reason for the pasporta servo - essentially a free airbnb for esperantists who were travelling. As a young person I thought it was incredibly compelling that there was a language which would make me part of a subculture where anyone will host you while travelling. Nowadays there's couchsurfing.com, which simply has a larger subculture, and as such the pasporta servo is not that useful any more. But it was a clever way to address that challenge!
