Study Abroad is great, I'm in London right now (only one week left, waaah!) and am loving it. I was lucky tho, my big sister came with me and is my roomie, and in the flat next door are two KKGs from a different school (UF, I go to FSU) and we met them very early on and had a little Kappa family here in London.
Like valkyre said, Paris is wonderful, I went there for a weekend and loved it.
Have fun, and just send your sisters lots of postcards 'cuz I'm sure they'll miss you. Make sure you're still getting the minutes sent to you by e-mail so you feel included in what's going on back home. And maybe some of them could come visit you for spring break!!
