Hello all! This summer I want to go to Chamonix with the train from Brussels. Does someone have experience if it would be best for me to buy an interrail global 4 day pass + then have train reservation costs. Or just buy the train ticket without interrail, since I am not planning to visit any other destination and would only travel 2 days of the 4. At first glance I see that a train ticket one way costs abot 150 euros, but that is just an estimation I saw since the dates are not published already for the end of June. Thank you!
Edit: I will be traveling on 25th of June and back on the 2nd of July
