Urgent need reqiured
Hi, I bought 5 Eurail passes for my family including kiss and elderly. I would like to go to Rotterdam on 28th July from London. When I go to Planner to search all the available trains, I found that there are two trains at 6:16 and 8:16, no seat reservations are required. Does it mean that I can just get on the train? How about the seats? Does it mean no specifics seats or all are free seats?
Then I found that there are other available trains in the afternoon which charges 56 pounds for each seat reservation. When I click to book the seats, it says all the trains are fully booked. Can anyone give me some advice as I'm not familiar with the booking system? I'm nervous that I have a trip with kiss and elderly.
