As seen in the movies, Hogwarts is a pretty cool place. From the massive castle to being surrounded by magic, the kids of Hogwarts have it made. However, there are definitely perks that are way underrated.
Having sooo many cancelled exams because of that f----- HP and his family's past. Source
You live with your best friends without wanting to murder them. "Who didn't do the dishes this week?" No one, because that's what house elves are for. Source
Being able to find lost things using accio would really help me in my everyday life. Source
If you learn where the kitchen is and how to get in (tickle the pear in the painting until it laughs and turns into a doorhandle) then you have access to free unlimited food whenever you want.
Id honestly kill for that perk. Source
The library! The castle's been around for ages. They probably have an unparalleled collection. So much magic to learn about that literally nobody pays attention to in the books. Source
If you don't like your Defense teacher, wait a year and take it again. Source
Let's be honest though.
Pretty much every muggle born should be nose to the grindstone in that place.
I mean, wizard kids? Yeah sure, for them it's work and education and blah blah blah expected of them.
For muggle kids? From their perspective, it's like if you took a school system, but then at 11 it turns out that instead of marks, finishing homework means you can shoot fire or summon objects or some other superpower.
Edit:Gotta add this too, but even the most often described "boring class" (History of Magic) would be a f---ing treat compared to what muggle kids were used to. "Oh, it's regular history... but with giants and wizards and other magical shit? And even when it bogs on with dates and names, every once and a while some zany guy does something like shrink an entire village or try to take over the world? Sign me up."
I mean, you'd get to learn about Winston Churchill coordinating the war effort with wizards, then go home over the summer and post dank memes about Illuminati with your muggle friends without them really being any the wiser. Source
The convenience of travel - teleportation, broomsticks, etc. Don't need to worry about rising gas prices, fixing your car, etc. Source
The one that came to mind for me was that you'd never have to pay for shipping because you can have your trusty owl take anything anywhere for you. Source
The availability of the professors.
Have a question about class? No problem, you'll see them every meal period, not to mention the fact many of them patrol the halls and are willing to meet with students even late in the evening. Source
They talk about this in one of the books, but getting rid of any acne using a spell would be aaaaamazing. Source
There are literal ghosts flying around. Imagine what you would learn from actually having conversations with people who died centuries ago. Source
Tuition free housing, board, and education for seven years of a child's life is a pretty good deal for poorer families, although they would still need to scrounge up funds for books and school supplies apparently. Presumably the textbook makers of the magical world are as cutthroat as those in real life. Source
The library's restricted section. Not sure if your crush loves you back? A love potion will take the guesswork out of the equation. Would you like to become immortal by committing ritual murder and creating virtually indestructible soul-receptacles? Go for it.
Provided you don't subsequently try to murder the planet, it's unlikely anybody will notice.
Seriously, why is that section even there? "Welcome to your first day of medical school, students. See that door? Don't use it. That leads to the level 5 bio-quarantine lab we have here for no explicable reason. If you release the last samples of smallpox left in existence among the rest of the student population, we'll be very cross, which is why we put this one aging dotard in charge of security." Source
The spell where you can expand the internal size of something (like Hermione's purse or Newts briefcase.) I could literally carry around a house with me, or anything I could ever need inside a kickass fannypack or backpack. I could just wander the world and never stress about having supplies. Source
In the books when they talk about their "essays" they say they have to write "a foot of parchment" which is roughly the size of an A4 page so basically their homework is easy and doesn't take long at all.
So on top of going to a magical school with tons of amazing stuff, you also get hardly any homework. Source
How much shit you can get away with. Harry risked his own life and the lives of others on a regular basis and got rewarded for it. Hermione disfigured another student's face (possibly permanently) and nothing came of it. Not to mention all the shit the Weasley twins and the Marauders got up to. The Marauders even became animagi illegally under everyone's noses. If you're a Slytherin, Snape will let you off the hook no problem. Was Draco expelled for attempting to murder two students and the goddamn Headmaster? No. The worst anyone got was house points taken away and detention. Source
Those epic feasts all the time. I'd like to think of myself as a hefty Hufflepuff. Source
For me, it would be the sorting into houses of people similar to you. I know that classes still happen with other houses, but being surrounded by other people similar to you would be fantastic. Imagine, being someone who LOVES to learn for the sake of learning, surrounded by other people serious about learning... Or maybe instead you're a Slytherin who wants to find someone to plot with? BAM! You're surrounded by other people of like minds. Source
