Hi All!
I'll be visiting the UK and would like to purchase tickets for a one day trip to Paris and back. However, when looking up information, I'm a bit confused as to what to pay? Would like to do 1st class seats there, but I am reading that I also have to purchase a reservation. Can someone please guide me to a good website on purchasing tickets and what excited is needed? Also, do I need a global pass for this one day trip?
