My husband and I are set to embark on the Mariner later this month. It's our first time on the Mariner and we'd love to hear your tips.

What are your favorite spots on the ship for watching the world go by, relaxing, socializing, etc.?

What are your favorite stateroom locations? We're in a Category B Penthouse suite with a butler. We don't really think we'll use the butler services all that much but we'll see. How did you all find the butler service? Did he/she basically just handle room service and make restaurant reservations?

Any not-to-be-missed spots on the Mariner or other tips we should know about? Thanks!

Andrea
