2nd the dvd player we take our ps2 so we have game console and dvd in one! If you are driving and there is room pack your microwave if there isn't one. We also take a baking tray and frying pan (usually you end up with nothing or the smallest in the world! Where in Norfolk are you staying? There are loads supermarkets all over place so you wont need to bring much because you wont be too far away from one. I pack salt, pepper and margarine as it is always annoying to buy those brand new if you have loads at home also I take a tea towel and bleach for when I arrive just in case the kitchen/bathroom isn't very clean! Have a lovely time I live in Norfolk so if you want any tips on days out let me know.....BTW whats the talc for?
If you have a washing machine, just take some washing powder tablets, rather than a whole box of them - just enough for what you'll need for the week. If you can decant fabric conditioner into a smaller bottle, try that too.
I always take a small sharp knife, some plastic bowls for picnic lunches (bowls seem to be more sand resistant than plates) and some plastic food bags. A tea towel, kitchen roll and antibacterial cleaner are also on my list (in case its not as clean as I'd like).
If feeling very organised, I take the first night's tea with me, frozen so it defrosts on the way e.g. lasagne or fish pie. Also take milk and tea bags - then i can survive anything.
Before this years trip to Norfolk, I used up the eggs at home and made victoria sponge cake and cup cakes to take with us - which was lovely and homely to have with us.
I you have room and are staying in a caravan that doesn't have full heating take a couple of halogen or whatever heaters too take the chill off the bedrooms. Even one would do, you can have it in the kids room until they go to bed then move it too yours. Rooms are so small you would probably have to move it out anyway from the tiny twin ones. Oh and don't let owners see you taking the heaters in they don't like it .
