I found this one on Celebrity's shore-ex listings, but I can't find any info besides what's there. Depending on the vendor and particular boat they're using, it could be an interesting tour. As I mentioned, it's definately a new tour that I don't think you'll find any past reviews for.
Maybe Budget Queen or Karen can dig up something from the East Coast that I can't find sitting here in Juneau. She always seems to have those helpful tidbits of information that us locals don't even have.
The only way to keep everyone happy is to delete my signature completely.
If anyone wants advice from a life-long Alaskan resident, please don't hesitate to ask.
