Thanks for your replies, the big case isnt toooo heavy, i can lift it but it is quite heavy, so we will be dragging it by its wheels alot of the time
Instead of taking a case each we have put all our stuff in 1 large case between the 3 of us!
Then we have a sports bag full of snacks & drinks (which is heavy from the drinks, but we wont need this bag for on the way back)
