You can get around Europe surprisingly cheap. This tax is made so that the people you mention, who pay for hotels and services in the town are not discouraged, but the ones who just walk through spending nothing will avoid the place.

It's a start though

The fee will be payed only by people who stay in the city just for the day. The idea is to discourage this kind of "fast tourism" in favour of people who instead spend more days in the city (then of course, the actual efficacy of this method for reducing overcrowding is to be seen)

I mean how you describe your situation sounds like exactly what this tax is meaning to deal with. A big group of people (10 by your numbers?) who only come for the day to use the city like a free open air museum and maybe buy a meal there and then leave having added very little to the economy to the extent that you think €60 is too much to pay for your day there being a part of the extreme congestion the city has.

So if you're not going to come anymore this seems like mission accomplished.

Amsterdam has the same problem with cruise ship tourists. They pile into the city and spend little money and create a nuisance for everyone living here. I think both cities would be much better off without day trip tourists.

Yeah cruise tourists are extremely fucking annoying when they pile into city centers by the 100s. I recall hearing an economic analysis being done about them in Amsterdam and the short of it was that they cost the city more than they spend here. They don't buy hotel rooms locally and they eat the bulk of their meals aboard rather than in the city. So they're just a drain on infrastructure and law enforcement and clog up the streets not knowing where they should and shouldn't walk.

I also recall hearing that going on a cruise is one of the most polluting things a person can do in such a short period of time. They just need to stop being a thing at least until such a time as they are able to run on something other than fossil fuel.
