its on the disney college site, after u sign in, you gotta click on housing, and the have 360 picture where you can see the apartment, a bedroom and the pool. Last I checked patterson wasnt on the site tho, only vista/chatham. maybe this is updated? also, you can go on
youtube and search "patterson apartment" or whatever, people film their apartments, or post pictures on blogs, a lot of bloggers are on here. so theres ways you can do a little research to get a feel.
for what housing you should pick, it all depends on what your personality is or what you want. Vista is the oldest, known for partying/being dirty/whatever, closest to walgreens, wendys, chik fil a , so its the most convenient. probably the easiest to make friends at.
chatham is like the middle ground between vista and patterson..parties but is also quiet. I live here and love it. has nice pool, and is the first to be picked up by the bus/last to be dropped off..which is a plus when your tired and want to go home!
patterson, the newest and has the nicest kitchen, its own car wash area (just bring the soap!) and air conditioned laundry rooms (the others dont have this). Known to be more serious/goody-goody.
these are all generalizations by the way, not everyone at vista parties and not everyone at patterson is going to be reserved. but thought id add some details to help you make the decision.
plus, theres the chance you might not get to pick...unlikley but depending on the date, it might be like, oh, if you want to have a 2br, theres only that option at vista. if it comes to that, who cares, its all apart of the experience. I went into it hoping I got chatham but I wasn't going to be heartbroken if I didn't get it, either.
