unlike other hotels (westin, grand hyatt, Sofitel etc) that are located closer to downtown, park hyatt Melbourne does not seem to jack up their prices too much for the Australian open.
Usually, we book the cheapest room, and ask to upgrade to a nice cathedral suite, with view of the cathedral and fireplace, by using the hyatt diamond suite upgrades. The suite upgrades save you around $200 per night compared to a normal room.
This year we did not stay enough at hyatt, and hyatt dropped the status match program, so we did not ask for a suite upgrade, we booked (and paid !) for a suite, which is extremely rare for us to actually pay for suite.
Normally, we do not pay for a suite, just the cheapest room. But when I saw that park hyatt Melbourne offer very good rates for their suites, ($600) with free full breakfast, AND $100 dining PER night, especially when the price is much cheaper than other hotels in town for a normal room (westin and grand hyatt are at $700 per night around that time for the cheapest room), we booked the suite with amex FHR directly.
The best part is the $100 credit for dining: you can use it for in room dining, which we did. We order late late night dinner (1am) after the tennis.
The staff seem to have an extensive notes on you. They are prepared. they know right away we stayed many times there before, and which room we liked.
Last year we saw stan wawrinka in the lobby the night before his big match with nadal. Instead of sleeping, he was in the lobby drinking at midnight. We took pictures with stan, and wish him good luck.
Conclusion: hyatt diamond status this year is not worth it. You can usually book suites for cheaper than trying to maintain status at hyatt.
park hyatt lounge: one of the ONLY park hyatt that have a lounge. And what a lounge ! they serve good canapé and drinks selection before tennis at around 6:30pm
