Leaving Mon on Constellation to New Eng/Canada-. Have always used the spa services but as non-regulars at a gym feel kind of awkward about going into the gym area. Would like to use the treadmills (use it at home) & maybe take some of the beginner classes. Do you think we will be able to keep up? Usually see poeple who look like they know their way around & we don't want to be out of place. I know we paid for the same cruise & amenities but are beginners welcome or a nuisance? On Summit in March it seemed like a young crowd with rock music! Can't wait to cruise!
