We will dock in Rotterdam next May and hope to take the train to Brugges. While on the train, how do you handle your luggage? Do you keep it beside you? Store it on the train? We are also in our 70's and I'm just a little overwhelmed with train transfers, luggage, schedule, etc. After staying in Brugges for a few days, we will take the train to Amsterdam. Thx for your help.
