It's hard being a single parent. And quite frightening facing your first summer holiday alone with the kids.
I'm quite evangelical about campmates - low cost camping for single parents and their kids. 20% off until 1st December.
I have no links in anyway - just been twice and it's wonderful to be with other single parent families. So am shamelessly posting for traffic.

(And also High Adventure holidays but they're pricier although still brilliant value for money.)
