Just remember not to overpack, since cruise-ship cabins, no matter how luxurious, are more cramped than your average hotel room. It is advisable to leave any valuables in the safe provided in your cabin. Land Ahoy Stops in Alaska are generally classified in three categories, according to the Carnival Cruises spokesperson. An easy excursion involves very little exertion and will likely be more of a bus tour or a salmon bake than anything vigorous. Moderate outings are city tours that involve some walking.
Guides provided by the boat operators lead a variety of organized day trips.
Not all ships offer the same organized tours, but the excursions from each port are similar. Many cruisers prefer not to take a tour at all, and opt to walk around a town on their own. Juneau, the state capital, is a day stop on most of the cruise lines. From here you can tour the city by foot or on a bike, though the hills in town are steep. There is also ample opportunity to go flightseeing over glaciers or glacier trekking, head out on a wildlife or whale watching boat trip, spend the day hiking through alpine meadows, or go sport fishing.
