The hotels on this website are some of the cheaper locations (first two are in north cape whereas the second two are in cape may proper). Airbnb and vrbo rentals are plentiful in the area as well and might be a good option for families. There are also plenty of rentals in wildwood (wildwood crest is closer the the venue location) and are an option as well!
