Hi the times we have been abroad we have taken those mini cereals for the kids, snacksize aero bars, biscuits etc and have never had any problems, but not too sure on noodles etc.
We packed them in our case on our holiday to Lanzarote, so maybe you could try that when you go to gc.
I know what you mean by saving buying things over there as the euro being the way it is
We are off to GC in september and are having to save that little bit extra with the way things are at the moment
Have a good holiday!
