Where would people stand in terms of refunds from airline companies and hotels if Germany are still accepting visitors but certain regions, ie: Saxony, are locked down with everything from football grounds to bars and restaurants and Xmas markets closed? If the whole country is locked down with no flights allowed in, I've found it easy enough to get refunds from the airlines and hotels but I'd imagine it might be a bit more tricky if a scenario such as the one I've outlined becomes a reality.
Luckily, my current lay out for Leipzig is nowhere near as balls deep as yours. As I'm already due over in Germany with the other half for 6 nights which has been booked since long before the CL draw took place, the Leipzig game has just dropped handily for me and would only involve a return train journey from Hannover (not yet booked), 1 night's refundable accommodation at the Premier Inn (48 Euros), and the match ticket (£23) which I presume would also be refunded.
