hi rob and welcome,we have done exactly what you will be doing in june,go for it.
we went out for a holiday and bought a place in catalarik which is not far from calis,or anywhere for that matter, but quiet at night when you want a peaceful nights sleep.
so have a great time in june and research all the info on here because it helped us alot.
we are not from n/wales but not far away on the wirral,but also a fellow scouser
