Alaska is stunningly beautiful. The scenic wonders made the time well spent, but that is separate from our disappointing experiences on Navigator.
We found the overall attitude to be very different from other luxury ships, ie Seabourn, and very disappointing. The staff was superficially pleasant but mechanical, as long as we made routine requests they were okay. But if you want something out of the ordinary, expect to hear No.
We experienced disagreeable and argumentative responses from waiters, those at the Destination Services desk, and Reception. Four Seasons Hotel training might be of benefit.
