Extra activities before and after Canada & the Rockies Tour

Hi All,

I've booked a Canada and the Rockies tour for the 5th September.

I am planning on seeing a few of the sights in Vancouver and Whistler before and after the Contiki tour. Things that maybe aren't covered on the tour or I want to see for a longer length of time.

I thought maybe people would like to share their experiences or their travel plans of the things they have or want to do while they are in Canada to give me some ideas.

Here's my list so far...

~Whale Watching
~Rocky Mountaineer train ride from Vancouver to Whistler
~Aquarium in Vancouver
~Possibly take a trip to Seattle
~Grouse Mountain

Let me know your ideas - and if any of the above are worthwhile.

Thanks

Kat
