Surprise Wedding. Anyone had one, been to one, or have an opinion or advice for one? please!!

Liala

So after seeing my sister bombarded by everyone telling her how to have her wedding and being stressed for all of the things she didn't want to do but had to do, my SO and i have decided to have a surprise wedding.

We don't want all of the BS that people say and we want it our way.

Any advice on how to pull it off?

Or any parents out there who have children who did this and didn't like it?
