DD(8) knows we're going on holiday in August and this will be our main one. After I've had a crappy 12 months and DD's been overall a little star all year, I decided to book a 6 night break abroad in May half term, just me and DD. I've got an hotel booked the night before near to the airport and was planning on telling her were just going away for the night, which she's already excited about as she loves hotel stays for some reason 
My question is, at what point should I tell her? Or should I tell her now as I feel she's missing out on the build up and excitement?? Arghh I'm crap at keeping surprises
