I can get this list easily off the website, but it only goes back to March 2010 now.

It would be significantly been higher if Hyatt had better location/more competitive rates in some of the other cities I went to.

I believe award counts towards unique hotels too.

How do you get this from the website? Just looking through past billing or is there a specific link to unique stays?

Sweet! That'd push me up a few.

Go to your HGP under account details where they show your account activity.

Then click on view all to see all your activity in a single page.

You can then copy and paste the data into excel and sort it out.

right ...

account details -> filter by hotel stays -> view all.

Then select and copy the data, paste to a file using notepad or whatever. I noticed the fields were tab separated, with the property being the 3rd field, so on a mac in a terminal (or in a cygwin terminal window on windows):

cut -f 3 input-filename | sort | uniq > output-filename

gets you a unique list of properties from that data.
(Where input-filename and output-filename are ...)
cut -f 3 selects the 3rd tab delimited field
sort does a sort
uniq eliminates duplicate consecutive lines.


Given that it's the third field in a tab separated file, there's tons of ways to do the same thing.

Been loyal to Hyatt for 30 years, only for about 2 years I needed to move to Marriott due to Corporate guidelines.

in 2014, I received a free night for staying at 100 unique Hyatt hotels.
Many of them are unfortunately not a Hyatt anymore...

Since I'm new to Hyatt, my list is pretty short. There may be more from my past when I didn't care but these are all since beginning of 2015. Let's See:

Hyatt Regency Grand Cypress
Hyatt Place Orlando Convention Center
Hyatt Regency Orlando Airport
Grand Hyatt Tampa
Grand Hyatt Atlanta in Buckhead
Hyatt Regency Pier 66
Hyatt Regency Miami
Hyatt Place Washington DC/Downtown
Hyatt Regency Crystal City

And next month I'll be adding:
Andaz 5th Ave
Park Hyatt New York.

Gosh my list is longer than I thought! Especially considering that these all are from within a 15 month span.

Updating in July 2017:
Hyatt Regency Orlando
Hyatt House New Orleans/Downtown
Hyatt Place Orlando/Universal
Hyatt Place Chesapeake/Greenbrier
Hyatt Regency Jacksonville Riverfront
Hyatt Place Tampa Airport/Westshore

HH Belmont/Redwood Shores

Next month adding
HR SFO Airport

PH Dubai
PH Maldives

I am a relatively new member so my list is short (and I tend to repeat the same trip patterns):

GH San Antonio
GH Washington DC
HR Chicago O'Hare
HR North Houston
HR Houston
HR Houston Galleria
HR San Francisco
HR Santa Clara
HR Crystal City
HR San Antonio
