I think a Sia-like storage solution, in the long term, should be drastically cheaper than a centralized product. The reason is that it's - at least partly - using unused space, and that there are potentially billions of providers.

I thought that it is already drastically cheaper than centralized solutions right now.
From the Sia website:
Far More Affordable
On average, Sia's decentralized cloud storage costs 90% less than
incumbent cloud storage providers. Storing 1TB of files on Sia costs about $2 per month,
compared with $23 on Amazon S3.

For a single hotel, this is another example where you don't need the whole network to calculate your computation
because you need a centralized party "managing" it. As a hotel owner, you could simply create that "smart contract"
on your own servers - as a "standard software application". Why would you want thousands of nodes to compute that contract?
...
I wasn´t thinking about a single hotel, but rather about the big hotel companies that own
hundreds of hotels (e.g. Radisson Blu). But after reading your reply I have to admit that even in
this scenario there isn´t really a need for thousands of nodes to compute that contract.
I´ll post here again
when if I come up with a better idea. Coming up with useful
applications for smart contracts is incredibly hard in any case (even though all
the companies in the Ethereum Enterprise Alliance seem to disagree with me for now).
