you're a tourist, so if you go somewhere it won't be tourist free any more will it
just look at a listings magazine or website like time out or nme

staying anywhere normal in london is expensive
if you're so pathetically scared of being a victim because of the media hysteria you could stay somewhere outside london and just get the train into the city. example, the fairly new queen elizabeth line (colloquially known as the lizzy line) stretches as far as reading at its western end. the cost of the journey would easily be offset by the cheaper accommodation options
>Doctor Who.
there are doctor who walking tours in london and cardiff but you could just get a route map online and follow it yourself
there was a proper "doctor who experience" museum in cardiff but it closed a few years ago. considering that the show is such a massive part of british cultural history (even though the recent series have been shit) it's a shame there isn't a proper studio tour or something apart from temporary exhibitions
