Ok, you can get the 6X at its stop #3, on Queensway. It corresponds to Admiralty MTR.

Get a non-tourist Octopus card to handle the dates issue you mentioned (assuming you're coming back to HKG on a future trip). Otherwise, I'd just buy ride-by- ride. Most of your travel will likely be on the the MTR anyway.
