Not Hockeymom here, but we have only had it granted ONCE and that was til noon only.....our CM friend even made the call down to the front desk and pleaded our case for us (we are "magical, repeat guests, etc

), lol....they are hardnosed about late check outs!!!
I believe you should request it at check in at the front desk and they have told us to call down the day before and verify that they can grant the late check out.
Praline!!! Welcome back!!! Thanks for checking in! Can't wait to hear more details about your trip when you're rested up...maybe about Tuesday haha.

I think they just got done fixing a water main in Conch...or something big like that in Conch actually a few weeks ago.
Happy day,
