Here is how to USE that early housekeeping request to SUPPORT checking out early.
When you call the front desk to request early house keeping say that you just found out that there will be a conference call followed by a quick meeting of colleagues, in your room,, early. housekeeping needed ASAP.
Go to breakfast or take a walk. Once the housekeeping request is fulfilled, call the front desk and say that the news from that call and meeting means that you will have to change your travel plans immediately and you will need to check out in 5 minutes. Then, just do so.
It has always worked for me.
