From my personal experience going on vacation with small baby is more tiring than staying home 😅. I bring a hand pump instead so don't have to bother with so many parts. Can scald the parts in boiling water instead of sterilising.
I brought own playpen and used hot water to sterilise bottles and pump parts during my last staycation. Yes, having a vacation with kid is like moving house.
I bring my own mini hot pot and boil my own hot water sterilze.
Staycation with little one is just a change of location :p
