At most an extension to 12pm...anything later will end up another nights rate..
They held me to 2 pm
You may not be able to. Just keep your bags at the desk til the parade is over
Or you could skip being a schlep and store your luggage at check out, this way Housekeeping can clean your room in time for the next reservation. :)
Only when the hotel is fully booked they may not be able to let you have a late check out, because the expected other guests may check in at ant time from 12.00 noon. But the Sheraton's staff are always very nice. So if the rooms are not 100% fully occupied, they would definitely let you do it, up to 3 or before 3 p.m. I experienced it myself without any difficulties.
After 12pm that's another day also talk to management you may hold till 3pm
If you are an SPG member they usually allow it. Ask the desk.
