Plan was KPDX to KSEA in the Cessna 441. Mostly IFR conditions to Seattle up at 8000ft. All went well until near Seattle where I was cleared tp 6000 at Pilot's discretion. Shortly after I was instructed to descend to 1000 ft and then told to expect vectors for Runway 34L ILS. I came down to 1000' and then was given a couple of heading changes which had me scooting across the thresholds of the three runways ay Seattle and then a big loop around to intercept the ILS quite close in (5 miles from memory). Any idea why I would be given such a low level course. I was expecting maybe 3000'. Also in such circumstances am I able to say "Unable" Similarly I was told to reduce speed to 100 knots which is a bit slow. I am not sure if I had clicked to use the proper profile (senior moment!). It would be good if I could again say "Unable, request maintain 120" for example.
Cheers
