Having decided to give up my car meaning that all my fukture trips to visit my AC will be by train, an easy to use smallish suitcase is imperative for me.
I do have a cabin sized and a medium sized, four=wheeled soft cases. The medium sized one is too large for these trips out (3-4 days), but on my recent visit to my son in Warrington found the cabin sized one was rather too small.
I have now purchased the largest sized cabin sized hard case I could find, definitely far more room than my existing one, and will try that out a few weeks time on my 4 day visit to London.
As an ileostomist, have to give up room to take enough of these appliances when travelling, along with an small ice-cream container for my different medications. Always have more room in my case on my return trip than outward one.
I do have a large, extremely roomy, across the body, wide strap bag in which I carry as much as possible that I will need whilst travelling - specs, phone, kindle, zip folder with all tickets, etc. purse, masks, lippie, perfume, tissues, packed lunch (if required).
