OPEN THREAD: How to kill the hours between ceremony and reception?

I booked the reception venue, which we are only allowed to use after 6pm, way before booking the church. I did not know then that the church would only do a wedding at 1pm. So, assuming the ceremony lasts an hour, we have four hours to kill between the ceremony and the reception.

Question #1: Besides the hour or so it takes for pictures, what are some good ways for the wedding party to spend that time?

Question #2: What do I do about the guests? Most of them live in-town. I have provided a list of recommended restaurants, entertaining places, and events going on that day on our wedding website. Is that enough? -demilicious

You've already nailed the answer on question #2. As long as you provide your guests with lots of info as to how they can spend their time with suggestions like museums, arcades, place to catch happy hour, tourist attractions, and places where they can get lunch, you're golden. There have been lots of weddings with breaks between the ceremony and reception, I'm willing to bet that in all cases there were no great wedding guest uprisings and revolts. Whatever you do, just make sure plans are well-communicated with guests — you don't want folks disoriented.

Now what about you and the wedding party? You could totally go wedding photo crazy for hours — how cool is that!? Then you could schedule a lunch at a nearby restaurant with your gang. Or tell them to go on and eat without you while you and your brand new partner sneak in a little alone time action (if you catch my drift).
