Whatsonwhen.com is relaunching for the first time in six years with a major focus on multimedia content and mapping tools.
The global event and attraction website has added 500 new destination guides to summer resorts and winter ski locations.
A Google Maps mash-up has been included for each destination alongside Whatsonwhen-produced videos and photography.
The development marks a significant ramping up of activity on the site, which also acts a content feed to a string of high profile travel sites including British Airways, Hilton Hotels, Lastminute.com, Travelocity, Hotels.com and Eurostar.
The existing hotel guides and entertainment listings for each location have also been improved as part of the overhaul of the site.
On-site weather information is also included for the first courtesy of a partnership with global information service Weather.com.
Whatsonwhen is part of the John Wiley group and was originally launched in 1999.
