Hi all,
This will be my first cruise and I have chosen Alaska!!! I was wondering which cruise line is the best for 20 something year olds? And on that cruise line which is the best deck for getting a balcony? I haven't researched the ships yet because I don't want to do any unnecessary work as this is supposed to be enjoyable!

I want to cruise for 7 days leaving from Seattle and hopefully going on a kayaking excursion!
Thanks so much for the help!!
