General Alaska tips!
Have fun in Alaska! I've booked tours with both the ship and on my own, and each has advantages and disadvantages. In Alaska lots of stuff is avialable shoreside, usually cheaper than aboard ship. Here are a couple of tips.
Juneau
Lots to do here. I have not done a helicpoter tour but they are highly recommended by almost everyone. I have done a flightseeing tour and felt it was a great value for the dollar. I was actually booked thru the ship but weather forced a cancellatiion. I then booked a later time directly with the operator and saved quite a bit. As I was traveling alone I got a seat, but if you have a family I would not count on being able to get a last minute seat. Seaplane base is very close to the ships location, right downtown. I have also done the Taku Lodge trip and enjoyed it very much although the flight only went directly there, IMHO they could have detoured slightly and given us a much better view.
Mendenhall Glacier can be booked directly on the pier with several different companies at 1/2 the price of aboard ship. I've even taken the city bus. Mt Roberts is also nice if a bit pricey. Don't buy tickets for this aboard ship, if the weather is bad when you arrive you're stuck with the ticket. Instead buy directly at the Tram if the weather looks good.
Next trip I'm booked with Orca/Capt Larry for a whale watch tour, I've heard lots of good stuff about this trip.
Skagway
Everyone does the Yukon and White Pass railway here it seems. I did it on my first trip and did enjoy it, sit on the left side as you leave the ship. Book directly thru the ship for thsi one, they discurage direct booking and the one time I tried it they were sold out.
My suggestion also would be to take a combo tour, the train up and a bus back. You'll see more and the ride back down on the train gets old fast.
I did the Yukon trip and thought it was great but I had perfect weather. If you have several people I'd rent a car and do it on my own. By driving you will save time and can stop where you want. Be sure and hook up with one of the National Park Ranger led walks around town, they tell great stories and give you a real taste of what life was like.
Haven't done a flightseeing here but this is the spot to try this if you missed it in Juneau.
Ketchican
There are sevearl Totem park tours here, I wasn't thrilled with the one I did. If I had booked ashore rather than thru the cruise line I would probably have felt it was better worth the cost. I've also tried the Misty Fjords flightseeeing but we had to turn around because of fog. Celebrity refuned the full cost even though we had almost 1 hour in the air. Another time I booked with Island Wings but I cancelled at the last minute as I was also doing the Taku Lodge in Juneau. They were very nice and I've heard very good things about them. Usually I just wander around town here, be sure and visit Creek Street.
Sitka
Haven't taken any tour here, again I usually just wander around. The Totem State park is within walking distance and has a nice trail thru the woods. Close by is the Raptor center and this is worth a visit. By walking yourself you can save big bucks over the ships tour to the same spots, total walk is proabably only 3-4 miles tops.
General tips
Take along binoculars. I also bring a knit ski cap, gloves and a scarf for glacier viewing on the open decks. The cruise into/out of Skagway is very scenic, and I like the area around Seward a lot. Be sure to get outside on deck to really experience Alaska. Try to get up for a sunrise and I really really enjoy the long twlight evenings. I find that when at Glacier bay, College Fjord or Hubbard as soon as the ship starts to leave the area everyone heads inside. Instead I head for the aft deck, bundle up in a blanket and lie on a deck chair out of the wind and enjoy the spectacular scenery virtually alone.
Have fun and enjoy!
