You've just arrived in Equestria and been offer a place to stay.

[Mjctechguy 193]

Fluttershy and her cottage

[Denim&Venöm 16,704]

In a castle by one of the princesses. 5 star accommodations. And I'm pretty sure I can get some sustenance imported or something. I'd be living the high life. 

[Kyoshi Frost Wolf 40,440]

Most likely it would be Fluttershy or Pinkie Pie, but I would stay at Pinkie's. I love food and she would be really entertaining, but my shyness would counter it a bit. I would eventually get over it though, Pinkie would be too fun.

Probably Applejack. As I've said before, someone needs to talk some sense into that pony's business choices!

[Love//Hack 819]

I'd like to sleep at Twilight's castle since it seems like a REALLY nice place to rest in and who wouldn't want to sleep in a fancy castle like that? I'd also go to Twilight's library and read some of her books maybe; most likely her Daring Do books. Maybe I could talk to Spike just for fun if Twilight doesn't want to talk. I'd also be able to talk to the other Mane Six if they visit at least.

Process of elimination.

 

Not Fluttershy's cottage, unless I want to get mauled by a bear.

 

Not Rainbow Dash's place, it's made of freakin' clouds.

 

Not Applejack's farm. I'd hate farmwork. 

 

Not Rarity's boutique. Though not outwardly disadvantageous, but the building itself looks rather small. I doubt there'd be a spare room.

 

Leaving me with Sugarcube Corner, or Twilight's tr... Oh right, it's a castle now. She'd probably have plenty of spare room for me, and a free pancake breakfast to boot. Sounds like my best bet.

[ChikaChan 7,321]

I would stay with Applejack,since I sorta like doing farm work anyway

[Rainboom Dash 1,055]

Twilight's castle has lots of room and facilities...

[RarityFan01 2,444]

 

Not Rarity's boutique. Though not outwardly disadvantageous, but the building itself looks rather small. I doubt there'd be a spare room.

 

From the interior, the Carousel Boutique is actually pretty big. It actually seems bigger on the inside. 

 

Then again, Sugar Cube Corners is HUGE!!!

real question, are we still human while we are there?

[TFarrgon 57]

I'd hang with Twilight. Her personality is exactly like mine and we would have so much in common.

[Lightning Roller 158]

I'd have to say lily blossom lol I wanna avoid the obvious mane 6 answers and pick a background pony. Get to wander around cloudsdale and see what all goes on up there

[GuyNamedEarl 1,332]

Fluttershy's cottage or Applejack ' house.

[SilverFlameWolf 47]

I believe Twilight would offer...and I'd sleep on blankets on the floor. Or we'd stay up all night and talk about books, maybe.

[Caliboom 219]

Twilight. I would sleep anywhere, as long as it is good.
