Thanks for the welcome.

KarenS- Have sailed on Diamond and Mariner a few times.

Whittier Transfer - Unless Radisson has earlier train service, it will probably be better to hire shuttles to transfer to Anchorage. Takes less time, will be available at our schedule and should run around same price as the transfer train.

Just started looking last night, will try to get a hold of these companies to find out the fine details and see if they will customize for a group.
Other companies:
Alaska Railroad

Alaska Group Tours

Will also look into price difference between 4 hour and 8 hour Denali bus ride. By the time we get there, locals should know how much wild life is visible this year and how far in you have to go to see it.

gf - Thanks for TV Alert will be sure to TIVO
