My first alaska cruise I did round trip to glacier bay from vancouver. This next cruise - May 09 I am going south - leaving from anchorage and docking final day in vancouver. I did this because I want to fly back from vancouver - shorter time to home in Louisiana. No other reason as i'm a loss of which way to go too. As far as right or left - I settled that by getting an aft balcony so I can see both in one shot! We did it the first time and it was wonderful!
