From what I've heard about professionally done hair on the wedding day, it should end up being pretty much bullet proof and will not droop in a couple of hours. They'll use much more "product" in your hair than they would for a typical styling appointment. On the other hand, you are on a tight schedule. On the third hand, you are on such a tight schedule that even if it droops after a couple of hours, the wedding itself will already be over...

I agree that professionally done makeup is not a bad idea. If at all possible, do a practice run ahead of time. This will give you a chance to veto things you don't like when you have enough time to try other options. You also will want to wear makeup before your wedding day so that you don't feel so weird. Maybe get a couple of free makeup-counter makeovers in the weeks leading up to the wedding, then do the practice run. The makeovers will give you an opportunity to see if there are particular things you do and don't like, plus get you used to wearing makeup so that you don't feel overdone when no one else can even see the makeup. (Though if you do makeovers you should let the person know ahead of time that you don't plan to buy much, if anything. They work on commission and it's not fair to have them spend a ton of time if you know there's no way you'll buy. Or you can buy something small you might use like a lotion or cleanser. Going at off times is also not a bad idea--you won't be keeping them from other customers.)

That really sucks about Macy's! Bad Macy's! I hope you find another place you like without too much trouble. I recommend sending a disappointed letter if you have the time and inclination.
