Just a thought for breakfast ladies. I won't be able to make the rally as I'm now in WA - used to work at the Senate (ha-ha) but don't hold that against me! The Hyatt Hotel on Commonwealth Avenue is just down the road (literally) from Parliament House. This is where the MPs and Senators used to stay - not sure if they still do, this could work for you though. Anyway, from all accounts they do a bang up buffet breaky in the Promenade Cafe. As it's a hotel and can accommodate more people and it's close to where you want to go and you could walk to the House I thought it might be worth mentioning.
