Just got back from Slovenia Ljubljana, 4 day long weekend break.
Our NHS travel vaccination certificate was not accepted in a few places.
It was accepted by BA airline, at the airport, as part of the checking in process, but not at some restaurants and places of interest like entrance to castles.
We are also due to go to Lisbon next month. It doesn't say it's accepted there either.
Having googled it, the BBC says it's not. Or is but only in a few places. That's poor isn't it? I assume most places are just accepting it though. We we just unlucky that the few places were being pedantic? We argued the case and showed our recent test certificate aswell but they were insistent that their card reader / scanner couldn't accept it, so they couldn't let us in.
