I am planning to take the train from Lucerne to Zermatt. On the way, I would like to stop at Bern to see the town for a few hours. I want to confirm that there are luggage storage I can rent (large airline luggage) for a few hours and then come back to get it before continuing on to Zermatt. Do I need to make a reservation to ensure there is space because we have 3 luggage. And also, please confirm exactly where it is that I need to drop off/pick up.
Thanks,
Liz
