I would call and ask to be allowed to attend. Don't just show up. The "real" wedding may never happen; I know this from experience. If you are not allowed to come, don't give a wedding gift. If they ask why, tell them you are waiting for the real wedding.
I offer advise to my natural daughter. I told her that is my right as her father. I also told her that she is an adult and has the right to do what ever she wants including ignoring my advice. She used to ignore my advise at first. Gradually, she has started listening. Dad, it seems, is smarter the older she gets.
Be as involved as they are comfortable with. Just don't meddle. They will want much less involvement at first since they are just establishing their own identity as a couple. As their relationship matures, they will probably welcome more involvement as long as it is offered and not imposed. A good rule of thumb is don't offer advise until it is asked for.
JMHO
