Please note this is Accomodation only :
You can stay at a number of Eurocamp sites in northern France for £30 (making £5 each based on 6 sharing) a week staying in
a 6 person tent - These tents are very well equipped with kitchen, living area, bedrooms (with real beds) - The camp sites are all 4* with swimming pools, water slides, parks, restaurants, club houses. So lots to do for the little ones.
Also with Euro disney nearby you can combine a day or 2 there.
You can get the Ferry to calais and drive to these parks in no time - the nearest being only 13km from calais - Ferry costs can be as little as £30 with car (look out for special offers)
You can also use Tesco clubcard vouchers to pay for euro tunnel
To get this price I have selected 5th May for 7 nights - although eurocamp have pleanty of dates available at this price up to the middle of may (it starts to get alot more expensive then) This price is per tent but only if selected with 1 adult - If 2 adults are going you will need to make 2 seperate booking and will cost you £60.
