You might consider the Untethered Regimen where you take part of your basal insulin through an injection of a long-acting insulin (Lantus, Tresiba, etc.). This makes it easier to remove your pump for long periods of time because you always have some background insulin. I am not currently doing the Untethered Regimen but I’ve used it many times and it works great.
This previous post can give you some information: Untethered or POLI regime
