How early should you get to the ceremony?

Will you need to do anything once you get to the church? If you're ready to walk down the aisle when you leave your mom's house, I would think later is better - you'll be more comfortable waiting there than you would be at the church, unless there's a specific place there where you can wait comfortably. I arrived at the church five minutes before the ceremony was due to start - it would have been fifteen but we parked around the corner and waited for a bit so I wasn't too early (while guests were still arriving). It worked out perfectly - by the time I'd got out, sorted my train out, found the pageboys and flower girl and got them sorted to walk down the aisle, it was go-time.
