I created an Excel spreadsheet that lists all 420 Hyatt properties in Categories 1-6. It has columns for country/region and category so you can sort any way you like or search the whole list at once, and I also maintained the web links to each property's home page for your convenience. It is current as of today, 27 April 2010, but I do NOT guarantee its accuracy today or in the future. If in doubt, check with the official Hyatt list, since I in no way represent Hyatt in any capacity! Hotels may be added/removed/change categories at any time.
