Has anyone Integrated Expenses with a Reservation System such as Get There?

I am on a client who is looking at both Oracle Expenses Cloud and Concur.  The single element that would swing their decision is integration with a Travel Reservation System.  

Oracle says in its documentation that Expenses Cloud is built to integrate with "Get There" -- their corporate travel reservation partner.  

HOWEVER - they (and we) want to talk to someone -- anyone -- who has actually performed this integration.  To date we have searched and searched and have not found a single company who has both implemented Oracle Expenses Cloud AND integrated it with Get There (or any travel reservation system for that matter).
