My family of 4 will be traveling in early August from The Hague to Paris. I was about to buy tickets on Thalys.com from Rotterdam to Paris, thinking we would just buy tickets from The Hague to Rotterdam on the day of travel. But then, I checked loco2.com, which allowed me to try to buy a ticket from The Hague to Paris (thalys did not give me this option) and the ticket they cited is an intercity train from Den Haag HS to Brussels, and then Thalys Brussels to Paris. Which route is better? Or is there a better way to buy these tickets? I want to do it soon, before the cheaper fares sell out. Thanks for any advice!
