There is a bright side to their website being glitchy/not working.
I have recently made some super low My Elite rate bookings which appear only for certain dates (i.e., only Friday and Saturday night). This makes sense because the hotel is typically booked solid on weekdays and offers a price almost double for weekdays for business travelers vs weekends. However I noticed if you play around with the dates when searching by adding one day to the weekend before or after (possibly doing it a few times) The same weekend My Elite Rate gets added to the back end/front end of the weekend effectively giving you a four or five day stay for the same weekend MY Elite Rate. In my case I got a five day stay for $65 (Thursday - Tuesday), whereas the regular weekday stay was $159.
Add an old suite upgrade (Feb 28, 2014 expiry) that I shifted from a previous reservation to this new reservation and life is good. Still have my 4 diamond suite upgrades available to use.
Thank you Hyatt IT.
