The first articles I read about it, made it clear from both hotels and FIFA that all of this was standard practice. FIFA had a structured, detailed timeline of when they, and the hotel groups, would allow room availability at higher prices.
It was clear this wasn't the first time either had been involved. And Both will also have taken practice from other areas. Pretty much every ticket, to every big event is set out to fleece consumers.
FIFA, being FIFA, can never be greedy enough. So, along with "incentives" to host the thing, they have their fingers in deals for transport, merchandising, TV, and sponsorship.
The states are pulling them up for the transport fleecing too. A slightly closer look will see than mini-don Infantino is at it everywhere else too.
