Marriage at the registry office?

Just wondering how many of you have married at a registry office or your thoughts on this. My fiancé mentioned the idea of this tonight, so having the formality there by ourselves then spending the "wedding money" on a honeymoon trip for us and have a "wedding party" upon our return. This will be my second marriage and his first.. I'm not opposed to the idea.. but wanted someone else's thoughts so please share 😊
