I was looking at booking Giovanni's for the first and second night  on the Voyager TA next May, since the DW and I are both diamond plus at the BOGO offer listed in the benefits page.  When I put it in the cart it charges me for both people.  Is this something you can only do on board?  Can you do it for both nights?  Just trying to figure out how to use this perk that we have never used in the past, even though we are about 1/2 way to Pinnacle.     I know, you would think I would know
