We are heading out in two weeks flying from Little Rock to Chicago to Stockholm to Gothenburg. What is involved in clearing customs upon arrival? Any other tips or advice would be greatly appreciated. Our only out of country experience so far is Jamaica so we are not experienced travelers. We are heading south to Copenhagen on Monday and staying there outside the city but plan on doing some driving in Germany. We have to get the car back by 2:00 Friday and will head home on Saturday.
