Tonight, in my country (Netherlands) the PM announced that most measures are extended till May 20th. Everything is based on what our hospitals can handle. Yes, there are less people in the hospitals, there are less people in the ICs, but the figures are not where they should be to open up fully.
First opening up, as of May 11th, after Spring Break is over: schools & sports (open air) for children till 12 years old will be back in session, but with conditions. Classes will be split in half and alternate between schooldays, for sports it means no competitions, shower at home, no parents supporting while kids are training.
Restaurants, theaters, museums etc. will remain closed, work from home as much as possible, no unnecessary travel, 6ft distance. Shops have always been able to remain open, provided they could take the necessary measures. For now hairdressers and nail salons etc also remain closed, but we will get an update in the coming weeks. No events till September 1st.
Our PM mentioned during tonight's press conference about the contact he has with fellow PMs to discuss how each country is handling the crisis and how they make their decisions. And I think we can say in Europe we are following each other's example. Germany cancelled Oktoberfest, not entirely sure if the Berlin Marathon got cancelled (according to media yes, according to someone in the Run threads not).
Based on what I heard tonight, my guess is that in Europe tourist attractions will reopen this summer, however I think countries will only allow domestic tourists, and maybe (limited) EU visitors. So even if Disney can find a way to cruise, I don't think any cruise ship will be allowed in any EU country this summer.
The only ones I might see happening are the cruises from Denmark, but I would say the chance is very small.
I heard the national airline is now at 10% of their flights, prediction is at the end of 2020 it will be at 40%.
