We are also off on Monday in our touring caravan and I always take too much - "everything but the kitchen sink" is the family expression! There is only me and Hubby going for 8 days, I always take food with me to last most of the week, but this year I'm not going to - there is an Aldi 2 miles from us so all I take is a good meal for when we arrive. I take a flask of hot water so as soon as we get our pitch, the first priority is a cuppa, even before we have connected the electricity. I take clothes for all weathers (you have to on our holidays!) but always take too many, especially dressy kind of clothes which i never wear unless we go out for a "posh" meal.
Enjoy your holiday Jenarry, which area are you off to? We are only going 80 miles across to the East coast where we have found a hidden gem of a caravan park, adults only, immaculate and an immense beach nearby with oodles of space even on a Bank Holiday!
