The reservations only restuarant is so popular that CCL is thinking about again raising the cost! That should tell you just how popular it is. They must be doing something right anyway. For the tours I highly suggest that you examine the tour guide and information packet that will be in your cabin when you embark and then make your decision based on what YOU want to do. Book early as the more popular ones do sell out quickly. Evening dining will have two formal nights when you are requested to wear at least a dark suit for men and dress for the ladies but many if not most dress to the nines. Other nights are a nice dress, pantsuit etc like you would wear to an office or nice dining restuarant, men wear dockers and collered shirt or dress pants and shirt and maybe a tie. Enjoy your cruise and check the reviews and the photo gallery.
