Surely you would confirm accommodation first and then the security arrangements? Obviously the lines are being manipulated to the obvious effect of trying to inspire sympathy, which hasn't worked. I can see there being an element of the Palace not wishing to be associated with the ANL judgement however it doesn't play out that they would have made the offer and then rescinded it 'just cause'. They would have had to make their own arrangements, PH would have needed to confirm he was going to stay there for that to happen. They didn't get a response, so they stopped making plans.
A bit like not receiving an RSVP to a child's birthday party from an invitee, you assume they're not coming so you don't make the extra sandwich/party bag. Inevitably they turn up and the parents get stroppy because little Johnny didn't get anything for attending.
#HamDram at its finest.
