me and my boyfriend want to take an alaskan cruise sometime in july or august. what i would like to know is do a lot of people take their kids on those cruises? which cruise line is the best. i have already done some researching and it looks like all of them have the good and bad, but which one caters to young adults (i.e im 23 and my boyfriend is 26) we don't want a lot of older couples and little kids running around
