Sounds like no one's really organized anything for the event, in which case why did we put our cities name down?As soon as the result was announced, hotel bookings went through the roof, customers who have made long standing bookings have had their rooms cancelled for suprioys reasons such as "card problems", "booking issues" or "terms and conditions"etc all of which is blatant lies, their rooms got relisted at 4x the original price, this tarnishes Liverpool hotel reputation with lots of angry people being put out, transport infrastructure can cope as long as it's not sustained, if too many use the train all at the same time we will have issues.
I'm lucky to live only 10 miles on a main line to Liverpool I would still expect some impact on public transport.
If I was in charge, I'd be looking to see what hotels are along the Merseyrail network, outside of Liverpool, and encouraging people to use those, with Merseyrail taking the brunt of transportation use. At least that's a network the people of Liverpool can take into their own hands, rather than relying on the dreadful TOCs.
