call the front desk on your check out day and ask if you can have extended hours.
you could inquire the night before you check out as they should have the list of rooms that will be occupied for the next day.
depending on the occupancy level of the hotel, you can get an hour or two for a late check out.
check out is 11:00.
i have used the late check out many times.
i usually get a 1:00 or 2:00 time period.
(probably due to being a platinum you first member)
those that book the AE package receive a 4:00 late check out at pbh.
