Planning a trip for next year to have something to look forward to. We will be going with 2DC (4&2) for four days and it'll probably include the older one's birthday. We'll be going for 4 days I think, half board. How much money should we plan for a few meals out, snacks and for buying toys/treats? Bearing in mind one of the days, we'd be extra generous for DC. Any advice would be great
