YCAT - Haneda Bus Times

From Haneda to Tokyo Station there is also a bus every 30 minutes. And then I guess from Tokyo Station to Shinbashi a taxi for a couple of thousand yen...

Total fare for two people would be:

Taxi Hotel to YCAT 1000
Bus to Haneda 1120 (560 x 2)
Bus to Tokyo 1800 (900 x 2)
Taxi to Hotel 2000

Total about 6000 Yen for 2

Time: Probably about 2 hours.......

I'm not sure that this would be the most efficient method. But with trolleys on hand at all transfer points, probably not that difficult with a couple of bags.
