For those of you who have had/are planning a Courthouse wedding before your ceremony.

So due to many financial and personal reasons (too many to list actually) FH and I are planning on getting married this week at the courthouse. So sudden! Yes we are still having our Disney World wedding, yes I am still wearing a huge ballgown, and out of respect for FSIL whose wedding is in June we are not telling people until after her wedding. So I have a few questions for those who have done/ are doing this. So my questions are this 1.) How long does it take? 2.) If you need a witness do you bring someone with you, or is it just like a random worker of that day, can you bring a witness? 3.) What do I wear, I was thinking like a special occasion dress, but on t.v. you always see like jeans and a tee-shirt. And my last question is did you do something afterwards? Yes this is just the "legal" part, but it is still the day I marry the love of my life and would like to do something special afterwards.(nothing big, but I need some suggestions) Thanks Ladies and Gents!
