The only “disadvantage” is that you have to pick-up personally the tickets at the train station. Actually I had to buy an additional ticket to pick-it up. It would be more efficient if the customer get the digital tickets to be loaded in a smartphone!!

we decided to buy the 48 hour travel pass for travel in the allowed zones. We caught about 10 trams & 1 bus which was the day of leaving to the station. It's very good value, I paid £28.00 online, before arriving to Amsterdam which seems the better option to do and downloaded the app I got it on.which gives you your ticket Once in Amsterdam you go opposite the train station where the TRAMS start there are 2 exits from train station BUS side TRAM side. Go into the white building to exchange your ticket for your actual travel ticket 🎟️. You can buy them straight from the place without buying online too. When you first use the ticket you scan them on the bus /tram. You won't miss it. Everyone does this.including the locals. you must also scan it getting off on every travel you take. Be aware not to have your phone near this system otherwise you might get charge on it with your phone even if you didn't tap it as it's WiFi. As we had this issue so got charged €3.00 from our bank

Because GPS did not work on my phone I had trouble working out how to travel to different parts of Amsterdam on the trams. It would have helped to have lists of the stops for each tram so that I could see which trams to take and where to change to get a different tram. Possibly this information is available for tourists, but I could not find it. However the tram driver were all helpful in explaining when to get off for a particular place e.g. the Museum Quarter and the money I paid for the pass was very good value for money.
