Düsseldorf. Anyone going? I’m boatshow starved.

I was seriously intending to go but on checking the latest info I saw that masks were required on all transport in Germany. I'm not intending to start futile arguments about the things on this thread but for me personally they're enough to make the show a 'no go'.
 
Brilliant show of boats and associated bits, including diving etc. pity there's no free local transport this time.
Are the 9 euro tickets still going? (9 euros for 1 month unlimited travel on local trains, busses and trams all over Germany).
