i absolutely wholeheartedly recommend it - best day of my life. so, advice:

1) include things from throughout your marriage that are memorable to you - maybe it's ceremony music, or the gown you wore the first time, or a poem you read while you were dating... make each and every element of your event about you and your partner, because it's a celebration of the time you have already spent together as much as it's a promise for the future.

2) involve your whole family - whether you have children, or furbabies, or a SIL you love, whatever it is, they have made your couplehood great, so make sure they are a part of it.

3) this is your time to shine. you're married!!! and so whatever politics you had at your wedding, or at the start of your marriage, put it aside and do whatever it is that you and your partner want to do. no rules, just love. :)

good luck with the planning!
