I'm not sure if it's only Hampshire, but I've noticed their Easter holiday dates are from 3-17 April 2015. This is a week later than all the other areas that I've looked at which are 30 Mar-10 April 2015.
I thought this would be useful information for any Hampshire dwellers as it's an opportunity to beat the school holiday prices. I've managed to book a really cheap cruise to the Canaries as they think we're coming back 'in the school term'. 
Hope that helps someone.
