Hyatt has the tiniest footprint of all the major hotel points programs, and the idea of the partnership with SLH was to vastly increase presence in places where there was no branded Hyatt hotel. A great idea in principle, but for some reason it did not work out for Hyatt..

If Hilton has the exact same arrangement as Hyatt did then it will be a lame duck from the start, especially considering Hilton's worldwide footprint is much larger.

If Hilton members want to be motivated to book these properties the benefits have to be near identical to what Gold and Diamonds get as a normal Hilton branded property. Also, it can't be cheaper to book direct on SLH's website.

Not sure what Hilton gains from this except some extra presence in some well off countries with low populations.
