As long as someone in your party (who is willing/able to pay) has an AP, you will be able to get the AP discounts. Usually, the AP holder has to be the one that pays (i.e., they won't always allow you to show you AP and then have someone else pay). So, let's say you have the AP and your husband does not yet. You can get the merchandise and dining discounts, but most likely you will have to handle the payment of the merchandise or the dining bill. If you husband is by himself, then he will not be able to get the AP discounts on things.
