The Hyatt late checkout benefit is a favorite, but often problematic benefit for exactly one reason: According to my, erm, “completely scientific” measurements, housekeeping will knock on the door and sometimes even enter your room way before your late-checkout time 147.1% of the time. The Flyertalk threads about late checkout confirm this measurement, making it even more, erm, “completely scientific”.
Recently I found a nice solution to knock that percentage way down, possibly to zero:
Put a sticky note over the keycard reader that says “4:00 PM Checkout” (“16.00 Checkout” if you’re outside the US and therefore don’t operate on freedom time).
I’ve never been to a hotel front desk that didn’t have a stack of sticky notes at every station at the front desk, so you probably don’t even need to pack your own set.
Now you can make sure the housekeeping staff has had plenty of time to caffeinate before they discover this nonsense.
