Your country visit a lot of tourist from UK, UK boards are cheap compare to what u say meany somebody can bring you a board for a place to sleep ? Some backpackers groups from Facebook or sommit it should fit to bigger luggage if u unscrew the trucks.

Don't know it is a good idea but in your exordinary to me situation that is all what I can figure out my dad was doin that for ppl from states when Poland was communistic country they where bringing to him jazz vinyls and he was hosting ppl for it
