We're seasoned UK holiday campers but looking at taking the euro tunnel to France this summer in July with 2 kids aged 4 and 1. We'd like great camping within 3-4 hours drive of Calais where we could potentially take a day trips to Disney Paris and coastal towns. Would have loved to go to La Rochelle or nearby but it's quite a long drive by the looks of it and then quite a way to Paris...though we could potentially leave that for another time. Any suggestions welcome!
