I want to see both Seattle and Vancouver and do a short stop in Victoria.
How does this sound:

Day one (Friday), fly into Victoria arriving around 11AM or 4PM depending on the flight. See sights around the center of Victoria and stay overnight.
Day two, helicopter from Victoria into Vancouver Harbor after checking out of hotel around 11am. Spend the rest of the afternoon seeing sites in walking distance of the harbor.
Day 3 (Sunday) take public transit or hop on hop off tour bus to see more of Vancouver.
Day 4 Visit Capilano suspension bridge park in morning, then go to Grouse Mountain via bus or train to see what there to see and do there in winter other than skiing.
Day 5 Take Amtrak train to Seattle, check into hotel.
Day 6-7 sightseeing via public transit in Seattle.
Day 8 fly home via Seattle.

Does this sound like good way to see these cities in that time period?
