Assume you have all the luxuries of a modern life in your Tardis (toilet, hot showers, TV, books, game console, …) which doubles as a mini self-sufficient apartment with it’s own energy stores and generation.
Where in history would you go if comfort wasn’t an issue?
I wanna visit the Indus Valley Civilization and see what they were about. If I’m not changing history I’m just gonna be a temporal tourist, hosting a livestream where I ask Romans where the best fast food is at and stuff.
