Best tour/cruise companies?

[bopbop]

My husband and I would like to travel to Svalbard in August. We would like to cruise in order to see polar bears and other wildlife. We have traveled with Lindblad before and had a fantastic experience. They have tours to Svalbard but I'd like to learn about other good companies as well. Can anyone recommend a few tour companies that are reputable and experienced in wildlife/ecotourism?

Those looking to take either a Svalbard cruise or North Pole cruise are good looking at specialist companies who control Arctic Circle cruises during the year using specially built modern ships with ice strengthened hulls and which are little plenty to get into the small ports of the Arctic Circle.
