Three of those were actually at the same property (Hyatt Regency Clearwater Beach) when we visited three years in a row. On each occasion we booked their standard room, and ended up getting the upgrade to their one-bedroom Gulf-front suite. ^

The other time was a couple of years ago at the Grand Hyatt Seattle when they upgraded us from their standard room to their Emerald Suite.

But, these are definitely not common for a Platinum member, so they've come as a pleasant surprise.
