I don't know anything about them, but I wouldn't expect a "tour". For transportation they are good options if you want independent and availibilty is very limited. For a 1 1/2 hour ride- I wouldn't be too concerned. Even if seated in the middle- you will have views but from Whittier try to get a driver's side seat. opposite from Anchorage for full views of the Arm. If you want more touring and sightseeing options then do a one way rental with Avis. Best option of all with the ability to see some of Anchorage and for a quick stop to Walmart if needed.
