Hyatt Gold Passport has my absolute favorite hotel benefit: Diamond members get to confirm a suite at booking 4 times per year (up to 7 nights at a time). Instead of hoping for an upgrade close to arrival or at the check-in counter, you throw down one of your trump cards and your base-level room reservation confirms into a suite, provided that the hotel has base-level suites for sale.
Hyatt’s Jeff Zidell tells me that they’re going to be announcing a change to the way that Diamond Suite Upgrades work later today.
