I am usually a rucksack user and very rarely use suitcases but will be travelling alone with 4 and 8 year old and have a bit of a bad back sometimes so am thinking about getting something with wheels, maybe a big holdall or soft suitcase. But when I see people with them they often look quite stooped and the bags seem to topple over. Do you find them helpful? Does anyone have any specific recommendations? Not too expensive please!
Thanks in advance
