Dave W. Thanks for your reply. Here is some information I got from the ferry
link below.
http://www.akferry.org/

I did this because of your comments and many comments I received when I
posted to the RV Net open forum at the link below.

If you go to my post you will see the many answers I received and what
prompted me to do this exercise to see what the costs  would be to stop at
some of the islands along the way (and stay at motels) as suggested by some
of those answers.

We are now considering just taking our car (no T. Trailer) on the ferry and
planning a trip of this nature. On the return trip we would leave Juneau or
Anchorage (by ferry w/car) and stop at 3 different locations on the way to
Bellingham.

As you can tell, we haven't completely decided and I'm going to pursue it
further.

If you want to e-mail me direct it would be OK.      meflanni@onemain.com

     Estimated costs from Bellingham to Ketchikan
     2 Adult Fares -  $420.00
     2 Senior Fares -  $210.00
     Vehicle up to 19 feet  $544.00

     2 Berth Cabin, Outside, Complete Facilities -  $226.00
     Total Estimated Cost -  $1,400.00

     Estimated costs from Ketchikan to Sitka
     2 Adult Fares -  $146.00
     2 Senior Fares -  $73.00
     Vehicle up to 19 feet  $180.00

     2 Berth Cabin, Outside, Complete Facilities -  $78.00
     Total Estimated Cost -  $477.00

     Estimated costs from Sitka to Juneau
     2 Adult Fares -  $78.00
     2 Senior Fares -  $39.00
     Vehicle up to 19 feet  $81.00

     2 Berth Cabin, Outside, Complete Facilities -  $51.00
     Total Estimated Cost -  $249.00

$1400 + $477 + $249 = $2126

     Estimated costs from Juneau to Skagway
     2 Adult Fares -  $88.00
     2 Senior Fares -  $44.00
     Vehicle up to 19 feet  $98.00

     2 Berth Cabin, Outside, Complete Facilities -  $57.00
     Total Estimated Cost -  $287.00

Hope this is of some help to you.
