Now we are using THB Voyager theme for a travel agency website in China. This is an amazing travel theme of wordpress and fits all our needs. The problem is the trip module has some map fields which developed with google map apis and now google is completely blocked in China. To enable THB Voyager theme works in China, we need to customize the trip module and frontend map with bingmaps and remove all google codes.
In frontend, we need to use bingmaps instead of googlemaps and leave the original functions work, such as map markers and it's links to trip stops section in page, and line connections between map pins etc.
It's much more complicated in backend, the trip module is developed from native google maps api, admin users has options to edit global position in realtime, to enable map dots connection, to modify map style and layouts, and more useful features of google map. All features is well integrated with trip fields of wordpress.
