Both are good suggestions.  I believe it may be prudent to try the YP video first for the whole crew, since that should probably be done anyway.  We do have a female adviser on all of our trips, but it is an ever-changing roster (a couple per year), as we have not managed to nail down a permanent female adviser, yet.  As such, our girls don't have time to get to know a female adviser.  We have just started a new school year, with two new advisers, so hopefully, we will get to the point where at least one (if not both) could talk to the girls if method #1 doesn't appear to work.
