I have used 5 plugins for the following features:
1)social media icons so they can be updated, & clicked on by users
2) events - to book & pay for
3) google calendar plugin to display upcoming events
4) slider to display the most recent events, & pictures of the centre
5) I have used 'image widget' plugin for 6 footer widgets - including a google map, ebook download and small banner
Should I have used this many plugins? I can't think of a way to reduce the amount. I have also used around 10 widgets, but have been told this is common with genesis websites and not a issue.
