Will be cruising the inside passage in September. Can use ANY suggestions about helicopter tours. Should I book through Princess.com? Is is better to take a helicopter tour in Juneau or Skagway? Can you get to the port and catch a helicopter ride or should you book in advance? Is it worth $200? Lots of questions, I know, but I have never been to that part of the world -- getting excited though! I've always cruised the Caribbean.
