I am heading to spain to stay w my in laws next week. I was considering just taking hand luggage for myself and my 3 y o. i was going to get him one of those ride on TRUCKI bags. Ha anyone got one? Are they any good? Would I be able to fit light packing for a 3 y o for 6 nights? i.e. 4 t shirts, 2 trousers, wet suit, 2 pjs, 6 nappies, 2 cardi's. What do you think?
