outlook - Display Exchange multiple room / resource calendars in one SharePoint calendar - Group or Team Calendar -

setup: sharepoint 2013 enterprise server on-premise , exchange 2010 server.

i want able pull in multiple room calendars exchange 1 single sharepoint calendar. allow users @ room availability in 1 screen , them book meeting @ time they'd it. ideally able book meeting right calendar. want able out of box if possible.

one other use set calendar entire team can see availability in 1 screen.

know can these things in outlook client wanted know if possible ootb in sharepoint.

i've tried bunch of things including activating hidden feature group work lists (which no longer accessible via ui in 2013, used available 2010) , creating calendars group team turned on, etc.

i've tried hidden calendar webpart allows show personal calendar - not interested in that.

i've tried page viewer trick , point url owa url, give me 1 calendar , not multiple , have set owa single sign on - rather not if don't have to.

i know there's bunch of webparts can buy (or code 1 myself) looking see if there's available out of box.

thanks
