For the first time since having kids, we've booked a self catering holiday rather than all inclusive. I've no idea how to work out roughly how much spending money we're going to need. I don't intend to prepare food at all, other than maybe the odd sandwich etc. Kids are 17 and 15, plus DP and I. Neither of us are big drinkers. Intend doing maximum of 4 day trips over the two weeks. Does anyone have a formula for deciding how much their daily budget is that I could use. How much do you spend when you're self catering?
