Many of the wiki guidebooks are CC-by-SA 2.5 licensed. OpenGuides seem more oriented to residents of a city, where Wikivoyage is oriented towards travellers.
Site is basically dead, but some good content may be rescued from old versions in the article histories prior to spambot destruction.
Likely the most important source of cross-site collaboration with Wikivoyage, most of the raw data for our maps nowadays comes from OSM, a user-generated, open-content map of the world. See Project:Mapmaking Expedition, Project:How to draw a map, and Project:How to create a map#SVG imports from OSM for ideas on how we can benefit from OSM content. They can benefit from our help too, and work on OSM in the spirit of reciprocity is greatly encouraged.

see also: Cooperating with Wikipedia
A project to create a free encyclopedia. It was one of the models that Wikivoyage was based on, and we use the software (MediaWiki) developed for Wikipedia. We link to Wikipedia, they link to us, and we often share content between the two, as our licenses are fully compatible. (If you import text from Wikipedia, be sure to use Template:Wikipedia to indicate that!)
Our progenitor site, where many of us first came together to start writing about travel. Many of our travel guides and operational conventions were begun there. Our licenses are compatible, so don't be afraid to bring over useful travel information — as long as you attribute it properly!
see also: Cooperating with Wikioverland A wiki specifically for people travelling with vehicles (4x4s, motorbikes, etc.), designed to supplement Wikivoyage with the very specific and detailed information needed by travellers with a vehicle.
WikiOverland includes sections like customs paperwork and fees, the process at the border, extending a stay, exiting with a vehicle, vehicle insurance, up-to-date gasoline prices (in any currency and unit the reader chooses), gasoline frequency and quality, camping, roads, checkpoints, bribery, vehicle shipping, maps, navigation, vehicle maintenance, buying and selling vehicles and much, much more.
