Yes. Numbers are based on those that pre-registered (can’t buy a ticket unless you did) so the band reflects the top 1600 who did so (or whatever the allocation is) rather than what it would be for ‘normal’ away games…….
Amsterdam around £1000 for two of us plane and hotel (expensive flight booked late stuffed me here ). Athens hotel €190 for 2 nights (walking distance from the stadium) and flight using Avios.
