Not really.
It may be inconvenient to use the Stadium for this Meeting. They would have to pay Staff - at least for Security, Health and Safety etc..
If they disagree to hold the Meeting at the Stadium there could be lots of reasons why it would not be possible.
I, as much as anyone, want Coventry to continue as one of the top venues in the Country.
But to say that "we know where we stand dont we!" if they refuse the use of the Stadium is possibly reading too much in to it.
