Ask HN: Find the highest rated entries on a Google Map section

So I'm planning a vacation to Thailand and I'm using a custom map in Google Maps to label points of interests I find in blogs and travel guides. Often Google already knows about them and people also already rated them. Now think about those ratings what you want, but if there is a 4.8 somewhere - I want to know!

So I was wondering if it's possible to find the highest rated entries in a Google Maps section. What do you think?
