I'm going to Center Parcs to have loads and loss of hardcore anal sex 
in September with my parents, DH and DTwins who will be five and a half months old.
They haven't yet been swimming so hoping to take them locally before hand.
I've been lots before but never with babies or children.
What are your top tips for things to do / things to take?
Also any swimming tips would be gratefully received - floats, swimwear, life vests...etc?
