I recently had a project where the customer asked for the Meeting Workspace template that used to be part of Sharepoint. I had to disappoint them as Microsoft has discontinued this feature for Sharepoint 2013.
Microsoft has put together articles with this and other features and services that are discontinued in Sharepoint 2013, they also give the reasoning behind why the features are discontinued.
As for the Meeting Workspace, this is the reason given by Microsoft: “Other collaboration features exist in SharePoint 2013 and Office 2013: Lync to conduct live meetings, OneNote to take notes during meetings, and SharePoint team site or My Site to store shared meeting notes.”
Here are a couple of links to Microsoft articles listing all the features discontinued in Sharepoint 2013.
