dd was 11 when we did a baltic cruise last summer. She LOVED the shipboard life - dressing up for dinner, kids club activities, pool, bar waiters making a huge fuss of her, family quiz competitions, etc etc etc. But she got less out of the shore excursions than the rest of us did - lots of listening to tour guides. We all loved cruising so much we are off again for Easter - to Houston and the Yucatan Peninsula. I am very envious of you re Alaska - think that might be our next one.
Alaska is fab - summer is really warm but beware of the mossies as they are brutal.
Are you going to just do the cruise or are you going to go inland at all - totally jealous I would love to do a cruise.
our cruise was one of the more informal ones - norwegian cruise line - with freestyle dining which meant you could choose where and when you ate and you didn't HAVE to get dressed up. So dh and ds could get away with jeans etc and dd and I could glam it up if we felt like it and not feel out of place.
Only slight downside to family cruising - we all shared a cabin with 4 bunks - me, dh, ds(16) and dd(11)!! Bit cramped and no nooky for a whole week!!!!
But as I said before we have all voted to go cruising again so the positives far outweigh the negatives.
