Did you call Hilton to set up both people on the same HH account ahead of time? Or just put in the same HH# on the credit card application?
In my case, my wife wasn't a Hilton Honors member, only me prior to our HGVC Resale purchase. I didn't even know you can have a share account. When we purchased HGVC, and I associated HGVC membership to my Hilton Honors account, they just send both of us in the mail Silver member cards for being HGVC owner. I never had it status prior to that.
That's when I learn that my wife now is now a Hilton Honors members without even applying, joining.
If you both are Hilton Honors members already, I would ask HGVC to help merge the accounts before applying for the credit cards, because during the credit card application process, it will ask for your Hilton Honors member number. If you were to merge accounts later after applying with different Hilton Honors numbers, when the accounts get merged, and one of the account will be closed, then you will have one credit card associated to the closed account that won't get credited properly. You would have to contact AMEX to update your Hilton Honors number later for that account that got closed.
If you get the accounts merged already, and share the same number, then applying separately for the credit cards is easy, just put the same account number in both credit card applications. Like I said, my case, I never had to call Hilton to setup anything ahead of time, just happened without me realizing it, but probably because my wife didn't not an account previously, and there was nothing to merge. I didn't have to worry about her losing points on an existing account because there wasn't one to start with. I would just verify on the HGVC dashboard if your names are both listed, and which account number is listed. Then if you both have separate Hilton Honors account, ask HGVC to merge the other account into the one listed on the dashboard.
This works out sure much better for the Aspire cards and Hilton Honors booking, than the Marriott system.
With Marriott Bonvoy, we both have separate accounts, and have to book the free 1 night stays separately back to back, and ask at the hotel for the two reservations to be merged together so we don't have to change rooms. With Hilton Honors, it's a seamless 2 night booking, I can see both free nights certs.
