Considering a trip to Alaska late June or early August. My first impulse is a cruise. We have never been to Alaska and would like to see glaciers,wildlife and perhaps some moderate hiking. My fiance has cruised in the Carribean,but his 16 year old son and I have never been on a cruise. Could somebody perhaps give me some advice on the curise lines? Is one better than another? We really don't want anything too formal. We will be coming from the east coast and packing light. Our budget is mid range. Can I do a 7 day cruise for approx. $1000 per person? What about cabins? I would love a balcony...It sounds departing from Vancover is the best option. I would appreciate any and all advice. My thinking is that a cruise would afford us the best bang for our buck,without us having to do all the planning,hotels,etc...is that accurate?
