I love the idea of thinking of it like what you'd do if they were guests at your home. Festive, welcoming, fun.
So I don't think I'd provide just in case convenience store etc. info. The hotel desk can tell them that if they need it.
I forgot to mention: resist any temptation to individualize the bags. The hotel will not appreciate it, and they will probably mess it up. If your friends are doing this for you, as is the custom in our community, you will be making their job harder, too.
At our son's wedding, my friends wanted to put coloring books and such in the bags for families with little ones, for example. It was a lovely thought, but I asked them please not to because I knew it would be a mess at the hotel. They distribute them as a courtesy, but when they're busy they can't be sorting through forty bags rather than just grabbing one from your carton. Even alphabetizing only helps so much, especially with several relatives with the same name.
Another time, a very gracious but rather controlling MOB gave a very specific list of guests' favorite candy bars, etc., to her "bag committee." I don't blame them for hating that. Much more time consuming and expensive than buying in bulk and doing an "assembly line" and not having to label each bag. It's just not that important to have a Baby Ruth instead of a Snickers, and as it wasn't even their friend herself doing it, the personal effect is diminished anyway. In fact, at some point it starts to draw focus from the wedding and onto what great hosts you are, KWIM?
I suppose if you are just doing, like, five bags, fine. But for a big group, do everyone a favor and just make them all the same, or different but randomly distributed as Lynn2000 suggested.
