How early should I add ‘my trip’ route on the Rail Planner app? For instance, suppose I arrive at Colmar and spent some time there, and then incidentally decide to leave to Switzerland with the train which is supposed to leave soon (like 5-10 minutes). Is it okay to add the train on ‘my trip’ on the Rail Planner app and use it?
In case I arrive in Milano at 11:40am, and would like to transfer a train to Venezia, is it okay to make seat reservation when I arrive in Milano on the day? If my condition is good, then I would visit Milano four 3-4 hours, and then ride a train to Venezia. However, if my co-travellers do not feel like visiting Milano and transfer directly to Venezia, can I make seat reservation and ride the train on the spot? It is going to be on 9, Aug.
Any advice will be greatly appreciated. Thank you in advance.
