I have found your many link approach to be very effective. While google seems to like it just fine, these pages rocket to the top when other groups link to them because they connect everything.
The local university linking to your page for things for alumni to do while visiting. A newspaper travel column that finds it easier to link to your page than try to list everything themselves.
Just a few links like this can lock you in a top spot for lots of local activities.
