Everyone gets Hyatt Diamond status or SPG Platinum status by just calling in and faxing some documents pointing out that he is a very frequent traveller, works for a certain company, 'owns' a certain amount of money etc.
It is not that difficult and one should not make a big fuss about it.
It is therefore of utmost importance for both SPG and Hyatt to differentiate between those 'el cheapo' comped guests and the real loyal customers and both have a somehow solid approach, one that continuously fails to deliver, unfortunately
