As a Level 5 Local Guide, you can:
Get access to test new Google products before public release
Apply to attend our Level 5 Local Guides summit
This is the highest level you can currently achieve with Google Local Guides. Other levels have nice Benefits. Like 1TB of Google Drive storage. I travel a lot for work and I tried to writing on a lot of different sites like Travelzoo, yelp, etc. I fixated on maps.google.com mainly because it is ubiquitous and fairly easy to add info. I hope you enjoy one of my piratical posts on any of the several hundred locations.
