Sue,
when we went to Alaska, I found that Radisson's air was $50 more pp than what I could book on my own. However, in checking out the flight schedules (and from info provided by Dolebludger) I found that because the flights would not get into Anchorage early enough to make boarding time in Seward, with Radisson's air, they would scheduled a forced overnight. In that case, they covered the cost of the hotel, you get breakfast in the morning and the transfers are included. This was on a southbound itn. By paying $50 pp more than I could have booked on my own, we saved the cost of the hotel and the transfer, plus we got breakfast.
