If the hotel ultimately owns the room then I'm pretty sure they would simply have software to look at exchanges on the chain and could charge you if you've swapped it. They could also simply not honor your booking. I think this is the point regarding "the real world" vs the idea of "digital ownership". You can have a token that says you get to stay a week in a given room and I (as the hotel) can say "no, this token is no longer valid within our system and the room has been rebooked". Crypto/blockchain can't enforce anything in the real world. The hotel though, backed by real-world laws, can say "there is an additional fee for swapping the reservation and you're outside of the refund period.". If you attempt to stay, you'll be arrested. So you see there's no actual power behind a digital representation of ownership unless governments (which crypto doesn't want involved) grant them.
