CentreParcs Europe have just put up most of their 2015 dates. Due to differences in French and UK school holidays you can get out-of-term ( depending on county... Hampshire is good ) bargains if you like CenterParcs and you're prepared to go to France. The pick of the bunch seems to be a short week ( 6 days ) at CenterParcs Lac D'Ailette week of 7th-13th April in a Comfort 4 person villa for £416. They're calling it a short week I assume because of Easter Monday when they don't seem to be taking arrivals. If you want 7 days you can go on Friday 3rd instead for a little extra. Equivalent week at Sherwood is £1448 ( 7 days ).
