Hotel Selections and Prices were made using Trivago (http://www.trivago.com/) . I would personally recommend Inn at Wilmington - Just Became Holiday Inn Select (Preferred by many of our regular customers) or The Days Inn on Concord Pike (Route 202) (Usually has the lowest price) as they are both conveniently located to restaurants and their prices tend to be Less than $100 per night. (Check Pricing on Trivago). They are about a 15 minute drive to our classroom.
The Crown Plaza is closest to our classroom (about 5 minute drive to Classroom), but there are very limited dining opportunities close to this hotel. We show hotels at Glen Mills, PA as an option, they are about 20 to 25 minute drive to our classroom.
The Comfort Inn Suites in New Jersey keep showing up as a viable motel, but you will have to pay bridge tolls and deal with rush hour I-95 Traffic, so this may not be a really great choice.
