Not wanting to jinx the Great Road Trip of '05, I will say that I have booked one night in Vancouver (well, Richmond actually, since it was cheaper) and after that, fate will guide us on our travels. A lot will depend on the weather -- if it is snowing through the Rockies, we won't drive that way.
Our options include a drive to Calgary with a side trip to Drumheller, a BC loop through the Okanagan, a dip into the U.S. (hubby joked after watching CSI that we could drive to Vegas -- though more likely we'd hit Seattle), or just stick around the Lower Mainland (Vancouver and area).
Most likely I think we will stay in the Lower Mainland. There is so much to do that even if we stay the whole week we won't get bored. I definitely want to take the kid to the Vancouver Aquarium, Granville Island, and maybe the Greater Vancouver Zoo, and I'd like to see the Coquitlam IKEA, and if we run out of stuff or feel bored we can drive further afield.
