Tens quare miles sounds right, a slong as it's not a perfect square, that would be silly. Also, this may help you out: http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/B/Biomes.html (http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/B/Biomes.html) It's a list of Biomes, and should be able to help you find and describe the exact geographical features of the island. I hope.<br/><br/>As far as room sizes go, I'd imagine that if it was a private, one person room (probably with a shared-by-one-other bathroom), the dimensions would be something like... 10 square feet by 13 square feet.  If this place is supposed to be posh, though, you could argue that student dorms are larger, probably something like 12x15 square feet. A professor's dorm room is like somewhere around 15x20 square feet, with their own private bathroom.<br/><br/>I'm just drawing numbers off the internet, of various people talking about college dorm sizes, and just roughly averaging them out for this.
