@Robert4992 It doesn't sound like a small thing at all. Travelling with large family requires planning, time booked off work, transportation arrangements, packing for many, etc. It's not something you just do spontaneously, like a single person or a couple might just decide to jump in their car and get away for the weekend.
I believe there is a lengthy thread on this forum re Evolve. Terrible experiences by both hosts and guests.
Personally I would never book an Airbnb managed by some big property management company. I'd look for something run by an individual host with a history of good reviews.
I hope you got a refund and are able to find somewhere else.
