Venice, a beautiful city built on water, tried a special ticket for people who visit for just one day.
The ticket cost €5 and was for people who arrived between 8:30 in the morning and 4 in the afternoon on some days.
The city thinks the ticket helped because there were fewer people on those days, but they want to check more carefully.
The city made a lot more money from the ticket than they thought, which makes some people wonder if the ticket really worked.
