Hi winnie1, when my two were that age, they used to go on PGL holidays. I was apprehensive about them going abroad, but they went to France and had a fantastic time. They also do hols in England.
PGL are the best in the business, the children had a fantastic time, and my son has been every year for two weeks, choosing to go with PGL rather than us!
They have allsorts to suit, sporty, theatre, language, fun, pony trekking, watersports, popstars, shopping etc. They are well supervised and age groups are controlled so no older boys to corrupt 14 yr old girls! Both DS and DD made lots of friends who they keep in contact with 4 years later and go and stay with, so that is a week accounted for!
I always booked in October for the next summer so got buy one get one free! They do special offers on their website, worth a look. PGL They have save 50% on some at the moment.
