Indeed, but it's more than unlikely they change that way that borders are opened earlier or soon. Also I think others are right the US with the current tactic will considered as high risk territory and while borders to Denmark or Austria may fully open in June (or perhaps even May) I can't see it for the US. If you follow the current discussion in Germany I think it's pretty clear you won't have a chance to enter Germany. Also consider many hotels are still open and were all the time but you can't stay as a tourist. Many hotels also sell their rooms as daytime office.
