Majestic ship exercise and spa (Alaska)

Is there a track around the ship that we can walk safely? I have crazy thoughts that we really might want to exercise! 😂 And we are thinking of using the spa for a treatment. I feel it would be worth the expense. I’m thinking the coconut 🥥 poultice for 50 or 75 minutes. Worth it? Splurge for sure 😄.
