Northern Lights tour out of Anchorage.

Has anyone ever done one or could recommend a company. Going in early September and this is one of the main things my wife wants to do. I tried to convince her that we needed to go to Anchorage and then up to Fairbanks for the best viewing but she is insisting we do a cruise. Flying to Anchorage and then cruising to Vancouver on Princes Cruise Lines. We are arriving the day prior to cruise leaving so we can do tour out of Anchorage but won’t have time to make it up to Fairbanks.
