Good luck carrying your own luggage Rudi - I have had to practically wrestle mine away from overenthusiastic bellboys - which is silly considering that I usually travel with a (heavy) laptop which I won't let anyone else take [they usually don't even try] & a (very light) overnight bag, as I seldom stay more than one night. If I have enough strength to lift it into the overhead locker on the aeroplane I can take it up in an elevator/flight of stairs myself!

This is particularly awkward when you arrive in a new country & don't have the right sort of currency/change. I suppose that you could just travel with a massive wad of US$1 bills & use those, but in some countries that is considered inappropriate.
