Hampton Inn Medical park is nice. It's a little bit farther away then some things, but it's in a really nice part of Wilmington. They have free breakfast, and wireless internet.
Holiday Inn Express (on Van Campen right between College Road and Market St.) is really nice too. (I like the other better though.) It also has a free breakfast and free wireless.
They are both probably around $130 depending on what room you get, and when you go.
