Doesn't sound right, I have no play in mine.
You say there's play in the derailleur even with the wheel off.
Can you see where it's wobbling from?
If it's the whole derailleur and the derailleur hanger, it's loose in the frame. So you would need to tighten the hanger bolt on the outside of the...
We recently stayed at the Speech House, really nice and bike friendly, also right on plot.

It was a balancing act keeping below the 32kg limit.
In the end I put the AXS derailleur and pedals in my carry on and put my riding boots, jacket and trousers with the bike.

I think the new size guide on the Pole website has been adjusted now, and it's pretty accurate now for me.
I ride a medium in most bikes and I would say the K1 is a medium.
