Just got back from the Star Princess two days ago. We have been there many times. As you get off the tender, you can find a 45 minute glass bottom boat tour to the arch. It costs $12 a person. We had very good water conditions and even went out around the point to the Pacific Ocean side. After, we walked 10 minutes to have a cold beer at one of the many nice restaurants on the water. BtW.. check the little map guide you will get.
Several stores in town give away free "tiny" ear rings and trinkets.
