If you are using Saga transport you will need to check that it is OK for 2 large cases and an overnight bag, as their 'allowance' is for 1 case per person. If you are on shared transport with maybe 3 other passengers, this could cause a problem. When we contacted Saga to ask if we could take 1 small holdall in addition to our cases we were told to check with the driver when he contacted us to arrange a pick-up but, of course, this would have been too late to re-arrange our packing!
