Thanks for the replies san888 and JDiver
I'm off the phone with Hilton Customer Care.
Hotel did not send the proper data for the credit to post I was told.
And although the 2 rooms were booked and paid under the same credit card due to the fact each room had different names on them (duh, It was updated when we handed the passports at check in) I'm being told I may not get points for both.
To be seen within 2 weeks when and if they credit. Come back as soon as it does to give details on it.
FWIW it was the Hilton Nuweiba Coral Resort
