I and my co-travelers want to take a train from Paris to Bruges. We have seen several sites to buy tickets in advance but TripAdvisor suggests only buying tickets directly from train companies rather than through an agency. We are not sure who the Train Companies are? We will be in Paris from 4/1-4/9 and want to travel to Bruges for a day trip on the 7th or 8th.
Can anyone tell us from whom we should buy tickets in advance?
