My husband and I renewed our vows almost 3 yrs ago. My husband went through a very serious bought of depression for nearly 2 years. It got so bad in the last few weeks that I was very close to having him admitted against his will because I knew he was suicidal. Anyhow, he had a breakthrough and sought help on his own.
As he got better he admitted to me that he had in fact cheated on me shortly before he started to get better. It was isolated and definetly over. (A whole other story)
Anyhow, after about a year I really felt I got to the point I had started to forgive him and he was making so much progress we decided to renew our vows. It was very important to us on so many levels. Anyhow, we were very private about it. The only one's who were present were myself, my husband, the pastor and a church witness. We did not invite anyone (not even my teenage son), because we did it for US. We also did not have a reception afterwards. We did go on a "second honeymoon" immediately following it. However, friends and family thought we were just going on vacation. Once again we kept it private because this was for us and only us. We did exchange new rings because I felt his ring was "tainted" in a way (because he had removed it the night he cheated on me).
We also did not do it on our original wedding anniversary, though that is the one we still celebrate.

My mother thinks huge weddings are a joke and it should just be the couple if it really means a lot. Go figure. We had a tiny wedding with just our parents and sisters that we paid for. I would have never expected or let our parents pay for a wedding unless they were muli millionaires. I think that is a strange custom.
We had Chinese food and champagne at DH's house after. If I won Powerball or was a millionaire you can bet I would have a HUGE bash for my 15th or 20th. 
Maybe eventually we'll do the Disney thing again, but by no means will we invite family or do the whole "invite people" thing. Just us and our kidlets.
