My nanny has just said she's taking a week of holiday in August. I'm going to take the week off work. We've not budgeted for a holiday then but I'd love to do something special with my 15 month old DS. We live in London, I'm thinking a few days away or a series of day trips in or out of London. Does anyone have any suggestions for day trips or where we could go for a few nights that wouldn't cost much? Budget about £1,000 in total.
