I'm relatively new to Hyatt and Hyatt's web site (ex-Starwood), but here's what I've noticed so far:

- I have 4 upcoming reservations and none of them provide details about the reservation under "Reservation Details" other than general hotel information and my confirmation number. Shouldn't it tell me what my room type booked is? The rate? Special requests, if any? You know, stuff that's specific to my reservation?

- I like using Passbook on my iPhone. It's handy to have all that stuff in one place, and kudos to Hyatt for making that a prominent feature online. Just a couple of notes about that: 1) it seems like the Passbook button in the confirmation email is missing one or more variables because if you have more than one email from Hyatt with the Passbook button in it, only the newest email will actually load the right hotel into Passbook. If you try to do that with a slightly older email from a different reservation, you still get the Passbook card for the newest email and hotel. Hope that makes sense. 2) I can't seem to find the Passbook button in my reservations within the Hyatt iOS app. Either I missed it or it isn't there, which would be a little eyebrow raising not to have iOS Passbook functionality built into your iOS app.

- When I search for Hyatts in Seoul, SK, seems like the results should include hotels at Incheon. I realize the airport is a fair distance away from central Seoul, but it still is Seoul's airport. I was initially shocked that there was no Hyatt property at the Seoul airport when searching on Hyatt.com. I ultimately found the property via a Google search.
