I will include a link to my webshots albums for you to look at my Alaska pictures. This alone may provide some explaination.
I am FAR from a good photographer, but, Alaska is full of photo opportunities. You will love it.
As for the tours. I have been fortunate enough to have done the Alaksa cruise twice. This enabled me to see things I missed the first time. I personally did not do any of the nature, fishing or whale watching tours.
They can be hit or miss. But, I will tell you those that went on some came back with some awesome photos. The ones I have of the bears & whales will speak for themsleves.
It can be very tough to make decisions for tours. Especially when they do offer so much. Go with what you love to see & do.
As for the money, some tours can be pricey, but, do provide a once in a lifetime look, right??
I can tell you those who did the Princess dogsled tours did not enjoy it & said it was not worth the money paid.
As for my helicopter/glacier walk worth every single penny. The one I booked left in the afternoon & was not the entire day so you might be able to get something booked for the morning. The Tram Ride downtown provides a great view IF it is a clear day.
You must take a quick visit to the Red Dog Saloon too.
Actually all of my tours were worth what I paid. Sadlt the weather did not cooperate either time I visited, but, ok.
The Seaplane ride was breathtaking. As well as the White Rail Pass.
With 6 of you in a group you may be able to book some tours independently & save some money. Read thru the posts here for tips.
You did not mention what ship you are on.
HOPE this helps some.
Feel free to ask away if you need more info.
