My friend and I are taking public transport from Munich Airport to Hotel Seibel in Theresienhohe during the Oktoberfest. We plan to take the S-bahn from the airport to Karlsplatz (Stachus) station where we will change to the U-bahn going west to get off at Schwanthalerhohe station, which is only a short walk from the hotel.
I heard that there is some building work going on at the Karlsplatz (Stachus) station and I want to know if this will affect the route we have to take to change from the S-bahn to the U-bahn. Can we still do this by descending from Level 3 to Level 5 within the station itself or do we have to go out through the streets?
