Allowing staff to view invitees and attendees to meetings in Room Calendars

I'm currently in the process of setting up Room finder and meeting rooms for the organisation I'm working for.  I've manged to get it all pretty much done but one request I've received is to allow everyone in the organisation to see not only the meeting name and organiser which I've already achieved using

\calendar -User default -AccessRights LimitedDetails

but also see everyone who is invited to the meetings and if they have accepted or declined. Is this possible at all? I've been trying to find a way but seem to be hitting a dead end. Even if give people delegated access to the room resource they still can't see it.

I would really appreciate hearing other peoples advice and experience on this and if it's even possible at all.

Many thanks
