Who knows what the restrictions will be like in a month or so; but I deferred some days in Amsterdam once I was there a day.
The two onerous restrictions are their lack of a system to show vaccinations for a non-European, meaning you need to test daily to go eat, have a drink, or go to a museum. Tests were difficult to schedule, and speedy walk up testing I found came to about 50 to 60 euro a day. If you have a valid covid pass from another European country, that would help, and possibly eliminate this hassle.
The other is reduced hours; all non-essential shops need to close at 6 PM, this also means many are delaying opening hours, so that in a small shop, the day can be covered in a shift. Restaurants and bars close at 8PM, but many places have just decided to close for the duration of the lockdown, or only open on weekends. There are also a number of places that closed with the first lockdowns, and just never reopened. If you have plans to go someplace to shop, eat, or drink; verify their hours
The experience itself was sort of surreal, few crowds, that may be great for some museums, but to honest, a lot of the life that I do enjoy of Amsterdam, just seemed to be lacking. It went from a peaceful quiet to a lonely one.
