thanks to all who have replied! this is great information to assist our planning - I was ending up with so much info off the 'net that it was getting confusing. We will be doing the ferry thing during the week, but I will make a ressie.

a couple other questions:
1) how much time will I need in total for the drive/ferry from Victoria to Tsawassen?

2) calculating that time, and the fact that we have to be back at Sea-Tac that night - anyone have recommendations for that last day? I list a few possibilities below, but am basically open to any suggestions!

thanks again!
