I visited the Medical Centre in December 2009 for an ear infection and I think the doctor's fee was approx. $60. US which was charged to my on board account. You then have to settle this with your insurance company when you return.
The ship rarely sails with empty cabins since they upgrade passengers already booked and then offer really low rates for lower grade cabins.
Automatic tipping is $11.00/day each and 15% is automatically added to all bar tabs.
Internet is $47.95 for two hours and it can be very, very slow at times eating up your minutes.
I also tip extra to my room steward and waiter BUT this can depend on their attitude, and extra service and whether I have asked for extra things. But you need not feel you must do this. Lots of time I have given them a heartfelt thank you and no extra cash.
