Hi, my family and another are going to Euro Disney on 20th July for five days. We are then planning to drive back upto the coast and stay somewhere about/within 100 miles from Eurotunnel, near or on the coast.

We are looking for a villa for 4 adults and 5 kids. Any Villa, location suggestions would be appreciated.

There's not much point picking an arbitrary 100 mile limit. The closest holiday areas where you have the nicest beaches and the best chance of finding accomodation is in Normandy and (further west) Britanny. These are well-connected via autoroute to Calais so would not take you long to get back.
Britanny ferries do holiday cottages, as do French Country Cottages, Chez Nous and plenty of others. You might also consider a Pierre et Vacances holiday "residence" where they do appartments and houses around a large communal pool and kids play area - some of these (benodet etc) are right on the beach.
