My fiancé and I would like to have a surprise wedding. My parents would know the details of our surprise wedding and his parents would help plan but wouldn't know the exact date of when we're getting married. The cover we came up with is hosting an engagement party. I was wondering if it was appropriate then to say that the engagement party is taking the place of the bridal shower and where we were registered. Should we also state that his divorced parents and my parents are hosting the event even though we plan on paying for it? And should we say that we are serving food and alcohol? I realize that we will have to let out of town guests in on the surprise so they can make arrangements to attend. Any help would be great!
