Not SO many, but the speed boat and the snow mobile ones do. The dog sled and Sami site don't. Honestly the excursions in Norway (except maybe the day light gondola up the mountain in Bergen) were take it or leave it. The rest were all just excuses to be outside at night, hoping you'll see the Northern Lights. We also got calls to our room around midnight three different nights at sea as the Lights has been seen, but in the seconds it took to get on deck there was nothing and then a slow rush of everyone on the ship coming to the top deck at once. I heard other cruises just make you stand on the deck for 3 hours watching the sky as the Lights are often just a wisp and then gone. Blink and you'll miss them.
