I'm trying to decide which tour to take:

From the reviews, I've decided on the following Kenai Fjords tours over others due to the amount of good reviews:

Kenai Fjords National Park tour 6 hr $139
Kenai Fjords National Park tour with stop at Fox island prime rib+salmon buffet dinner 8.5 hr $143 (special)
Kenai Fjords Northwestern Fjord 9.5 hr ($169)

I am ok with the timing of all 3, but is partial to the 6hr tour. It starts the earliest and get me back on the road at ~2pm. It is 6hr vs the next one up that is 8.5 hr, but I think only because dinner is not offered. However, the $4 extra for prime rib + salmon buffet is very attractive!

I am curious about the 9.5hr Northwestern Fjord since this is the longest tour. From googling, I learn that it enters the "quieter" Northwestern Fjords, which is much further, and you will see way more animals. Now, for $26 more, and no buffet dinner, will I just see "more", or are there Glaciers that are much more special in the Northwestern Fjord?
