Just like Trantor in the Foundation series by Issac Asimov actually.
Suspiciously like Trantor in the Foundation series, actually
Seriously,
Foundation is an undisputed SF world-building classic, and works as novels, but if Apple make a literal film-of-the-book it would consist of someone reading out the opening text crawl of
The Phantom Menace and being interrupted by a phone call saying that some kid has attacked the Death Star (oh and, spoiler warning, Jar Jar Binks turns out to be the real Palpatine...) - So, its either going to be outraged wails of "OMG, they changed the story!" from Asimov fans or snores from everybody else...
As for tourist destinations:
Any GSV or Orbital in the Culture, and when you're fed up with post-scarcity hedonism, join Contact for "interesting times".
Or, Discworld (provided you have fully paid-up Theives' Guild insurance and a pair of noseplugs and understand the Ankh-Morpork concept of avoiding "self-inflicted injury") - its like Middle Earth or Narnia, except it has a functioning economy* so you could eat hot meals and rent a room for the night, explore by public transport and even get WiFi (well, an almost pocket-sized pair of ping-pong bats to wave at the nearest semaphore tower...) and good healthcare (provided you avoid doctors like the plague and take the witch or Igor option...)
(* Seriously, did nobody else watch the LOTR movies and not think "hang on - that's a flood plain between two major cities, so why aren't those giant battle elephants struggling knee-deep in cabbages?" - The place consists entirely of fortresses and wilderness. I mean, the Shire could probably get by on self-sufficiency and smokeleaf exports, but nowhere appears to have any infrastructure or agriculture... and the Riders of Rohan are going to be mighty constipated without some veggies to go with all that horsemeat...)
