Shoretrips is only a booking agent they do not run any tours. I never recommmend them. They have been noted for screw ups in Alaska and know nothing about the tours.
Frankly, you are FAR better off just booking direct with the vender and not going through them. Superior for getting all your concerns directly answered and knowing exactly what company and their reputation. It you are looking for a wildlife tour, consider the listings www.sitka.org especially if you want to see puffins- your only accessable area on the Inside Passage. You will want a trip that includes St. Lazaria Island, not all do.
