I would visit Death Mountain in its Alttp Dark World form. There's something pretty cool about that place. Imagine actually walking through a bizarre area like that. Of course, this decision assumes I'm protected from being transformed into a tree or bunny.
Hm... tough one. If anywhere I'd need to say the top of the Tower of Spirits, because then I could look over all of Hyrule and see all the Spirit Tracks and trains that pass by. Plus if I got sick of it I could go hang out with Anjean or go find the compass of light within the alter there. (Of course I would also have the Phantom Sword and the Bow of Light.) I'd much rather hang with Anjean though.
I would go to the beach in mm, or maybe snow peak or like hyrule in tp, dragon roost in ww? or kokari (can't remember how to spell that) forest in oot? I DON"T KNOW! its all so pretty!
Well probably Kokiri forest because I'm the Green Link in Lozoot, and if I was in MM I would be in Clock Town, but if I was in WW Forest Haven, and if I was in MC I guess The Cloud Tops, because if I could find the roc cape because I could glide with it, and if I was in OoX it would be Labrynna because OoA is my favored over the two. Well I guess I like allot of places.
Let's see, OoT I would probably be at Hyrule town and play its expansive amoutn of games and stuff as well as try to befriend Zelda and get the OoT which means I could teleport wherever I wanted to. MM on the other hand probably the great bay or Snow Mountain.
I'd definitely choose Windfall Island! But only a day seems too short! I'd honestly want to spend my entire life on Windfall Island in the Great Sea! It's such a nice place!
If I could live in Hyrule I might be some kind of travelling merchant, I would collect items from dungeons and sell those. I would charge a very high price for all my items or you can have it for free but in return if I ask for a favour you must do it.
That or become some travelling swordsman learning, creating, sometimes teaching new skills.
