I know they read this... All you Hyatt fans know the problems:
1. Logging in/out (already logged in)?
2. Slow
3. Making future reservations and allowing to adjust check in/out days on the same page without hitting the "back" button the browser.
4. Listing the rates by day or adding the day, instead of calculating backward from the date of check in, to know what day # is costing $150 and not $125?

other than that thanks for FFN!
