I just have a few questions about using Eurostar trains. I always travel by Ferry (usually from Dover to Calais) when i have visited other countries so i have never used Eurostar yet (but i am considering possibly using it soon). If anyone has used Eurostar or knows the answer to these questions that would be much appreciated. Can you just turn up at the station on the day and buy a train ticket? If so what is latest that you can arrive at the station? And is there a website like www.brfares.com that shows their fares if you just turn up and buy on the day? Do you have to have a seat reservation? If so are you allowed to sit elsewhere if it is empty and are you allowed to stand? Do you have to get a ticket for a specific train? Or can you get a ticket that lets you use any train on that day (like National Rail tickets do). Can you break your journey? Is there any security and passport control? If so what does it involve? Is it very strict and are there lots of restrictions on what you can bring? Is it similar to Airport security (i have never been on an Airplane but have heard that Airport security is very strict)? Many thanks.
