Many thanks John.

Sounds good.
Had been to Whistler back in 2006 to give lectures, so not that much time for activities. But will do this time.

Looking for a good camper rental company. Booking from Germany is pretty expensive. We do not need the camper during our stay in Vancouver and in the US. Sounds like Vancouver transportation system is good and don't like to drive in Seattle with a long camper. In Portland we will visit long time friends and can you their house, pickup and trailer.

Haven't found a rental company that offers pickup at Vancouver and return at Portland.
We might take the train from Vancouver to Seattle and Seattle to Portland.
