I'm having my wedding at the Rose Garden this September. If you want to use the pavilion, make sure you get the permit. It allows you exclusive use of the gazebo. There are no chairs allowed (except for elderly or disabled) so keep that in mind. Because of the "standing room only" situation, plan on keeping that ceremony mildly small. The public is still allowed in the park, so be prepared for gawking or random strangers trying to watch.
