The Glacier is well worth seeing & Juneau Shore Tours offers a very competitive price. You can look high & low but you won't beat their price, especially if you combine a second city tour (Skagway).
The Skagway tour was a lot of fun, the tour guide was informative & entertaining. The minibus was comfortable, it was a small group & we exited the bus quite often to better see the sights. Really enjoyed the tour.
