I'll bump this up for you since no one has responded.
I've not stayed at PH, and will never.
I never forgave them for rude treatment at the TR desk many years ago.
Perhaps not typical, but there are too many better options to risk it.
I SUGGEST: Call your Host at Paris, or request to speak with someone in Paris VIP.
"We received this offer [have the info/number at hand] for PH, but we are loyal Paris people and much prefer Paris. Can you match this offer for us to stay at Paris instead of PH?"
I bet they will. If not, say "no thanks" to the PH offer, unless you want to try it.
And think ahead...if they offer you 4 nights instead of 5, will that be OK?
You'll probably get an offer for Paris soon anyway since you are a regular.
Good luck.
