You'll need more than a morning to do both Brooklands and MBW. I'd do one or the other if time is an issue.
Last time I was at a (non-MB) club meeting at Brooklands it took all day, albeit at a reasonably sedate pace, to do everything there. I didn't bother with Concord (its not one of the 'in service' aircraft - was a test bed plane - and so doesn't have the cabin fitted out for passenger use) and if you are not interested in aircraft at all then you would probably be able to do the rest of Brooklands justice in just a morning.
