Great familt break for whit week .
Midweek break - Mon to Fri 2 Adults + 2 Children Comfort Villa.
Erperheide is about 3 hours drive from Calais,or 2 hrs 20 min from Zeebrugge Price comes out at 302.02 Euros if you click young families discount and uncheck cancellation insurance.
You can get across the channel for well under £100 return - getting a hol abroad on the cheap! at center parcs quality! (Just Checked Norfolklines website - Calais - Dunkirk for this Hol - £46 return ferry - at mid morning departure and mid afternoon return 2 hrs 30 min drive to Erperheide)
We have been 6 times to this park and its FAB - everyone speaks English and approx 30% on guests are from UK.
Try the othe parks in Europe for prices as well - they will shock with how cheap they are compared to UK parks prices. They don't seem to hike up the prices for School half term hols etc.. However i believe July / August is expensive.
Got a feeling that the huge price difference between UK and Europeasn Center parcs might feature on tonights BBC watchdog.
