A rough idea of where we might meander : Fly to London > to Brussels and then to NL with the Eurostar. "Under water mum!!??", "yes!". Then down south to some islands Corsica (France), Sardinia (Italy) and Sicily (Italy). Then over mainland Italy to Greece to explore the Balkans : Albania, Montenegro, Serbia, Bosnia, Croatia, Slovenia, Austria, Czech and back through Germany to Scandanavia : Denmark, Sweden and Norway. And then hoping to catch a boat back to the Netherlands and head down to France and Spain at the end :)
