Worried as a first time traveller
Hey all, I'm hoping this is the right place to come to ask, I can't find anywhere better to, I'm visiting someone in France (I'm from and in the UK) for the first time, and this is the first time I'm travelling to France on my own, I'm going via trains, the London underground to the Eurostar to Paris, then TGV, I think it was, to metz. As any first time traveller it feels a little confusing and overwhelming and that's normal, but I was wondering if theres any suggestions anyone could give, how much time to leave between the Eurostar and TGV and how the security and stuff all works, that kind of thing to give me an insight to what I will or may face, I would ask about the whole journey but seeing as this is about travelling in France well, yea. Thanks for the help in advance
Also for me, the more detail the better, thanks
