I know Ix mentioned it a while back, and the idea of immortality sounds great and all, but thinking on this more and more I come to realize that any other option I think of is all subject to "Can I use that to get to the Whoniverse?"

I just... If I could find some way to just work on a TARDIS or-- dare I think it, badfic-y as it sounds-- use some kind of weird Time Lord version of CRISPR tech to let me pilot a TARDIS? Man, I'd give anything.

...I mean, surprise.

I would find me a nice queer posthuman future, stay long enough to recover from capitalism and learn how to bootstrap the future, and then bring it (and an awesome post-human body or three) back with me to start here.

I’ll portal to the DC universe, 50,000 BC, and soak up some of that meteorite radiation that Vandal Savage was exposed to. Hello immortality, enhanced healing and durability, increased intellect, and superhuman strength, speed, and endurance.

or any of his varying versions, Dannyland, Danny the Planet (not the ones where he's damaged and everyone's like dead, though).

He's a sentient travelling crossdressing street (he's covered in masculine stores selling guns and sports and such, but decorated in frills and so on) who's just, an absolute top bloke. He accepts in various outcasts and such and basically everyone is really nice, including of course Danny himself.

I just want everyone to be nice to me, man. Including the urban infrastructure.

I would love to go to Jurassic World (before everyone went bad, obviously). Seeing real live dinosaurs has been a dream of mine since I was little.

I'd stay a couple of weeks - long enough to get my own dæmon!

Go there, get a pilot's license, buy a ship, and set off among the stars. God I miss playing that game. I got a month's worth of one of the absolute best games I've ever had the pleasure of playing...and then they dropped Mac support. I loved that game, and I would have kept playing for sure. Problem is that I can't transfer my progress to a console version, and I'm kinda strapped for cash at the moment to get a PC. Well, another one, since my old one burned with my apartment.

I mean, come on, it's the crossroads of a number of my all-time favorite franchises! I'd get to meet a lot of my Nintendo heroes in person and it'd be wonderful, at least until I start to miss home of course. Sure, I might end up becoming a spirit thanks to Galeem, but if it means I can be equipped to Pit and help him against the World of Light, I'll take my chances. :D

Honorable mentions include popping into the world of The Incredibles for a week, if only for a chance to interact with Violet without my own messed-up author desires warping her OOC, and visiting Jurassic World, though I'd rather not stick around that one for long because as much as I love dinosaurs and such, I'd probably die like anyone else would once the inevitable breakout happens. :P

Seriously, this is a wonderful idea, and I hope you don't mind me asking this same question to other online communities I'm in! It'd be fascinating to see which worlds the people I know would want to be in, if only for a day. :)

I think I'd have to go to Pern. Post-Thread, if you please. Not just because Thread is dangerous, but because I'm curious to see how the world is getting on after a few generations or so after AIVAS.

I might try to join the Harper Hall (in whatever form it evolves into), I might be able to swing a dragon-ride pretty easily if some of them are career couriers now, and I would definitely stay however long it would take to Impress a fire-lizard. {= D

... Man, the more I think about it, the more I want to see and do and learn. This is a great idea. ^_^

Assuming you have the requisite magic and such, I'm heading to Garth Nix's Old Kingdom. Learn Charter Magic and swordfighting, possibly become a sworn sword-hand of either Sabriel or Lirael, defend the world against Free Magic and the Dead! And even if I died, I'd be able to find out what lay beyond Death and the starry sky, which I've wanted to know ever since I learned about it in Abhorsen.
Then when I come home, I can impress everyone with my wicked swordfighting skills. There's no quicker way to learn than life-or-death, amiright?
And if I could, I'd bring my best friend. I'd love to go on an adventure with her, especially since she introduced me to those books.

... is how you interact with the existing systems. Can you be assumed to have all the requisite paperwork and have it filed and such so that you, for example, are treated essentially as a recent, legal arrival in the area? Do you speak the language? If the setting is magical, do you possess such magic? For example, could you go into the Fate universe and participate in a Holy Grail War? If so, will your magic return with you? What financial resources do you have access to when you visit this other plane of existence? What influence can you wield? Do you, by visiting, gain knowledge of cultural norms enough that you can at least seem like somebody who comes from the same planet, even if you must have been hiding under a rock for most of your life?

1. Portal to the river from Tuck Everlasting.
   
   2. Spend roughly five seconds drinking from said river.
   
   3. Return home.
   
   4. Stories everlasting, zookeeper everlasting, doctorlit everlasting. Forever.
   
   —doctorlit is still supremely obsessed with living forever, if that wasn't clear

... and she immediately said 'bank vault'. I don't think she's planning on staying long. ^~

For myself, I would head to Nargothrond, the city that stood at the pinnacle of Noldorin culture in Middle-earth. I'd go sometime between the arrival of Men in Beleriand in 311, and the Dagor Bragollach in 455 (because no-one wants to hang around for the war). I'd stick around for long enough to learn conversational Sindarin; not sure how long that would be.

As for what I'd do... I'd explore. I'd talk. I'd find out all the things that Tolkien never recorded. I'd spend a lot of time in the library. ^^ I'd sneak in a camera and get pictures of all the art.

(I would consider visiting Valinor in the time of the Trees, too, except I'm pretty sure that would be harrowingly bad for a mortal body. Alas.)

I'd have to say the Mushroom Kingdom, for at least a month. Take in all the sights, ride a Yoshi, partake in a Mario Party, do a little kart racing, try and figure out how the desert world is usually so close to the ice world and such.
