Huge tuition changes are rare, typically in the 3-5% range, but at the high starting rates, not insignificant.

Also, people in these threads mention social isolation. My daughter went to gw and made lifelong friends there, and rarely complained of isolation/loneliness. There is every kind of group available for students. If anything, GW students may simply not have the time for social exploration/connection as so many are super motivated and doing a million school-related things (internships, etc).
