Look to explain this - again.
I realise that we are unlikely to get killed/injured.
My kids are autistic, what this means is that whenever we go on holiday we start preparing with visual schedules from 3 months ahead of time.
We sit them down to explain to them
Day 1: we will travel to the airport in our car, here is what the airport looks like, whenever you get into the airport this is what will happen, then on the plane they will do a safety briefing like this (video), we might get a snack on the plane - discussion of food, whenever we land we will pick up the bags and then exit the airport, here is what the airport in London looks like, we will get a train from X to Z here is what those stations look like, we will have lunch at X destination (has to be preplanned with known menu)…. Etc etc etc
A change in what is expected ie getting off at Gloucester Rd rather than Kensington High st, could result in anything from mild distress and agitation to a complete meltdown, hyperventilation or in the case of one of the children them lashing out and doing a runner.
It depends on what their tolerance level is at the time. For example if there are a few minor changes, probably ok, if substantial which for them would be 2-3 travel changes/missing out on seeing something big in the itinerary this is liable to result in up to 2 days of the holiday to be written off. Thankfully they haven’t had to experience an out of control protest/terrorism disruption, I would imagine this would write off the whole holiday.
I don’t want to spend a few thousand to sit in a hotel room rocking children to calm them thanks.
