'It's utterly unspoilt'

A day or so ago I came across a Twitter thread exploring the horrors that might eventuate from time-travel tourism - having to take the equivalent of Ryanair to get to your chosen epoch, vast crowds in Renaissance Florence and other hotspots -

So I thought, wouldn't you then get the other thing, the whole 'the Sun-King's Versailles is the new Benidorm', and people going for that really chic, utterly unspoilt, little nook of historical time?

No tourists, nobody there but the Real People of the Day -

(Only then, probably, word of it gets about and it gets Spoilt.)

The other thing was, the people who do Extreme Holidays would probably also do Extreme Time Travel (storming the Bastille? riding with the Golden Horde? the possibilities are many.)

I'm also wondering about the insurance implications: and having one's vaccination certificates up to date. I remember having to have a smallpox vaccination certificate when, I think, it had actually just been declared extinct but certain countries had not yet updated their entry requirements (no, it was in fact after the last naturally occurring case but before WHO declared official global eradication). But if you were going back pre 1980, maybe you should get that done? Anti-vaxxers not permitted to travel in time???
