@smc4761 I get your point about all the pump stuff you have to take with you when you go away.
Personally, I decided it was worth it because, when I go away I need to vary my basal more than usual ... because I exercise more constantly. But I get that you want a break.
One thing I realised when I was forced back to injections (due to pump failure) was I needed my basal injection as soon as I stopped the pump because I had no basal on board. From then on, I had to remember my basal at that time of day which was an inconvenient 3pm.
Given you are choosing to return to MDI, my hint would be to remove your pump at the time you want to do (and remember to do) your basal injections.
