I considered going but the 4 swabs and risk of getting stuck in Germany with covid are not worth it. If your pre departure test in Germany is positive, you cannot enter SG for 21 days.

Air tickets are cheap. Around 1k only, not 10k.

I visited Germany a few years back and have been to Frankfurt and took ICE train to Berlin...not much to see in Frankfurt as the city was entirely destroyed by bombing in the war, Berlin is historical and interesting as you can see a church that was partial destroyed by US bombing, Jewish cemetery outside parliament house, remaining stretch of  Berlin wall and Russian gigantic buildings in East Berlin...there is a tram as well.
