Everybody assumes that time travel would be easy: you press a button and you're immediately transported to another time. But why, given everything we know about the travel industry?
Time travel, a thread:

Let's say you want to travel to 1452 but it's expensive on a legacy carrier. It's 20% of the price on Easy Time Travel but they'll take you to 1449 and you have to make your way from there.

So you go off the no frills time travel and check another national carrier. They'll get you to 1452 but you have to have a layover in 1789 Paris for a few months.

So you give up and pay the higher price for the legacy carrier. Except you're seated between two screaming babies for six centuries.

Then you try to book a ticket for any time between 1889 and 1932, but everything is fully booked. You finally manage to get a ticket but security start drilling you. 'You're going back in time to kill Hitler, aren't you?

And obviously anywhere nice in history; Andalusia, Renaissance Florence, Timbuktu would be impossible to get to. But the travel agent would be like 'I can get you a cheap ticket for Europe during the Black Death?'

Avoid 33 AD, it's full of loud American tourists trying to stop the crucifixion of Jesus but they got lost and ended up in Morocco

You manage to get a ticket to Bethlehem for the birth of Jesus but there are no hotel rooms available at all

Half of Britain would go back to 1939 to relive the war and the other half would go back to 2016 to change the referendum result

Then try getting through the metal detectors with this on, on your way to a medieval battle

It will get really awkward when Adam and Eve notice all those tourists gawping at them and taking selfies
