Amazing location to have a ceremony. Also very pricey on weekends, so we did a mid-week wedding package (much less expensive) and had our ceremony on Friday afternoon. With mid-week, there are other folks walking around - we didn't mind this - but it's something to be aware of. We got married on the Mayor's balcony. They are clear that if the mayor needs it for an event you can get bumped to another spot. It worked out for us. Awesome spot to get married. Only reason for 4 stars (rather than 5) is to acknowledge some of the hassle associated with a public/gov't location.
