Seat Reservations from Lucerne (Switzerland) to Venice (Italy)

This seems like a bad connection. 

You should take the highspeed train from Milano to Venice. (less changes and your faster, reservation is 13€ per person)

You can buy the necessary reservation online from ÖBB without additional fees (Austrian Railway  https://www.oebb.at/ )by selecting Interrail/eurail under the discount selection.

If you miss a connecting train with mandatory reservations, you can exchange them free of charge for another train. Contact a ticket office for assistance.

If you can leave earlier, I suggest this connection, seat reservations are necessary only from Arth-Goldau to Venice:

The 4 minute change is short. But it should be possible, as the Swiss trains are usually on time.

Also reservations in Switzerland are mostly not necessary. (Almost noone reserves seats there)

Hello ​@Danhiel and ​@Marvin Heer - Thank you for your prompt responses. This will be our first time traveling to Europe as a family. From the below connection, do you think if it is feasible to change trains at Lugano within 4 minutes, considering that each of us will be carrying two suitcases?

 Thanks,

​@Venkata Kasturi If you want a bit more time for changing trains, why not take the connection that Danhiel posted it? Seems like the better option if you consider leaving arround that time.

But 4 min, while possible can be a bit of a hurry with a lot of luggage, as it the transfer is not on the same platform but on the one right next to it. (you have to cross the tracks via the underpass to the next platform)

2 suitcases per person is a lot of luggage. Try to minimise and book accommodation where you can wash your clothes.
