Who the hell wants to go to Westeros? Like…”Y’know what I want…some place where the bounty of the long-summer has been squandered and Winter is Coming..a place where your closest friends are either being shipped off to war or are already dead. And if there was an army of fucking frozen zombies riding undead elephants, bears, and direwolves, beating down the border, that would also be awesome…”
although with the acception of maybe Hogwarts, Westeros probably has the best food of the options presented here
(still, the answer is clearly Hogwarts, because they have canonical dental care and flush toilets)
Hogwarts is the best because it’s still in our world, so you get all the conveniences of modern society plus MAGIC, fantastical creatures, and awesome wizarding shit. Yeah you can’t use electricity at Hogwarts, but you can just go somewhere else and watch the latest Marvel movie or w/e and then come back. Plus did I mention apparating (which you can’t do inside Hogwarts but yes)?
All of those other options don’t even have air conditioning.
