We stopped here both weeks.  We had already booked tours for each week on our own.  The first week, we booked a Helicopter Tour of the Glaciers.  The second week, we booked a Whale Watching Tour.  We had to pay the full price for both of these in advance.  Week one, we had some time before our tour so we took the Mt Roberts Tramway up the mountain.  Once up the mountain, we took the loop hiking trail and made the side excursion to Father Brown's Cross.  The scenery and views were breathtaking (not to mention the hiking)!  Shortly before Noon, we caught our ride to Temsco Helicopters for our Pilot's Choice Tour.  This turned out to be a mixed experience.  We were scheduled to fly at 1 pm.  We arrived at their terminal and filled out the weight list.  Then we were shown the safety video.  As we were donning our glacier boots, we were called to the side and told that our aircraft had been diverted for med evac and we would need to reschedule.  A large number of cruise ship passengers were in the same room with us watching the safety video and donning boots.  It was awfully suspicious that we were being bumped but no cruise passengers were being bumped.  Especially considering that they try to put 6 passengers in each helicopter and there were only 4 of us.  They offered to put us on a Mendenhall Glacier tour (where would they get the helicopter for that) or book us for a Pilot's Choice Tour at 6:30 pm.  The ship was departing at 9:00 pm - the tour was 90 minutes long.  We felt that it was cutting it too close.  The people at Temsco assured us it was okay and that they had a Statendam shore excursion booked at the same time.  Given that info, we decided to take the 6:30 pm.  It turned out that the Temsco people told a little white lie.  There were other people from the Statendam on the 6:30 tour but it was not one of the Statendam's Shore Excursions.  Those people were on their own (like us).  This really messed us up because we lost a couple hours being bumped and then had to miss dinner to do the 6:30 tour.  When we returned for the 6:30 tour, I noticed that the flight board showed a full complement of flights for the entire day with a full load of passengers for each flight.  As we thought about it, we remembered some people complaining during the safety video that there weren't enough seats for everyone in the room.  We came to the conclusion that Temsco overbooked their flights and bumped us because we were on our own and not part of a ship's excursion.  I guess that is one of the dangers of going on your own.  But, we took the Pilot's Choice Tour and thoroughly enjoyed it.  We landed and walked around on two different glaciers, Gilkey Glacier and Herbert Glacier.  Seeing a glacier first hand while walking on it was awesome.  There were two helicopters that travelled together.  Both pilots were good tour guides.  At the second glacier, the pilot passed around champagne and chocolates.  Imagine that... walking around on a glacier 400 feet deep while drinking champagne and eating fudge!!  We also flew over numerous other glaciers.  Luckily, we reminded the pilots that we needed to be back on board by 8:30 pm and they hurriedly got us back to the airport on time.  Temsco didn't seem very organized but the tour was outstanding.  I would certainly recommend it.  The second week, we took the Orca Whale Watching Tour.  We were taken pretty far north of Juneau to board a jet boat.  There were about 25 people on the boat and there was just enough seating inside the boat for everyone.  This wasn't a problem because most of us were outside watching the whales.  The boat had a back deck and a top deck (limited to 6 people at a time when the boat is not changing location).  We only saw one Humpback Whale and he kept running away from us.  We saw a group of Sea Otters laying on a channel marker.  Then we saw a number of Killer Whales (Orcas).  The one Killer Whale began swimming parallel to our boat and our captain kept us in sync with it.  It repeatedly came up out of the water and showed it huge dorsal fin.  I shot up about a roll of film on that one whale.  It was a great tour.  I was very pleased with the boat and the limited number of people on the tour.  Some of those tours have these big boats where they pack as many people as possible on board to the point where you can't move around and get a good view of anything.  On this tour, everyone got to move around and get a good view of the whales.  Back in Juneau, there is plenty of shopping right across the street from where the ships dock.  We did some shopping the first week.  You can actually buy a fur-lined Jock Strap there.  No, I didn't get one but I was tempted.  Again, the ship had a complete assortment of shore excursions at Juneau and there appeared to be ample availability.  The tours aren't cheap... helicopter tours run from a low of $180 per person to $340 per person.
