Skagway- We spent the most on this excursion. The train trip was really spectacular, the lunch and show was good at the gold mining camp, and the brothel in town with drinks at the Red Onion Saloon was fun and was all included through Celebrity.
Seattle- Pike's Place Market, the needle, take the Water Taxi across for $3.50 to get the best view of Seattle and great Fish and Chips Shack right as you get off the taxi across the bay.
