Struggling to get a straight answer to what seems like a simple issue:

I currently have two Hilton HHonors memberships, one Silver, one Gold (the latter from here I think).

Due to sheer idiocy on my part, I've already put three stays through the Silver so far this year, before realising my mistake and switching to the Gold account.

Am I likely to be able to get Hilton to combine these two accounts and credit all the 2014 stays onto one account, and combine the points?

Would the combined account keep the Gold status?
