I drove by this hotel on my home from the train station. Can't tell you much about the inside except that the lobby and bar area looked nice. The hotel is in a pretty dead area of Wilmington. I don't know what there is to do around this area at night.
If you can swing it, check out the Courtyard Wilmington Brandywine. It can't be more than 5 miles away and has the benefit of having shops, malls and quite a few chain restaurants nearby. [Edited to add: I thought this hotel was built within the last 10 years...surprised to hear it's so worn down]
