Hello! I need to catch my high speed train from Paris Gare de Lyon 07:35 july 6th to Nice. Right now I’m in Amsterdam and i was planning to pass through Luxembourg for a few hours since i wanted to visit. I’m leaving on the 5th and I’m choosing between taking the flexibuss, therefore not visiting Luxembourg, or using regional trains. Is this route good? Will i get on board with out seat reservations? They’re greted out everywhere so its hard.
i also dont mind sleeping one night in a different town like Champagne, but I’m not a huge fan of Paris.
