A menu overlay (otherwise known as a custom tour) is a ‘layer’ that sits on top of your virtual tour giving the user a navigational guide around large spaces. We recommend this for very large spaces, hotels, shopping centres, stadiums, although this can be used for any business type.

This service does not directly sit on Google but can be linked to from there.

We can add 

1. information hot spots
2. popup boxes
3. navigational menus
4. video clips
5. online statistics 
6. and many more extras. 

The overlay is then embedded on your website where you can share with customers to view.
