I'll declare my allegiance before I start, I prefer Hilton, and growing to appreciate Marriott. There is no rational explanation for this, I think it is just historic.
However, if this thread has convinced me of one thing it is that any earings differentials between Hilton/Marriott/Hyatt are negligable.
The important factor for me is benefits at Elite level. I have no experience of the Elite levels of the Hyatt scheme so would be really interested in a comparison.
Ok, my experience based on Elite level benefits is that Hilton Internationals offer a superior level of benefit to Marriott's (upgrades etc). However, I find US Marriott's offer a higher level of benefit that US Hilton's.
To make that tangiable, I have always been upgraded to a suite/junior-suite at Hilton Internationals' but have found it hit and miss in the US. The reverse applies to Marriott's.
This may in part be because I am only Black in Marriott Rewards and Diamond in Hilton? Again, I would be interested in hearing other views.
I could easily be persuaded that my experience is not typical!
