We have been checking out what makes Crystal more expensive. As far as extra expense, no charge for, sodas, bottled water, alternative restuarants, ice cream, cappacinos. They keep sodas and bottled water stocked in your cabin. There are no charge cocktail parties. If you book a higher catagory cabin, you also get beer and wine in your cabin. We have been on quite a few cruises and this will be our 1st on a so-called more expensive line. As we read 1 person put it, we are going to be "Crystalized" From what we have found out the service is great, the food much better, and the atmosphere much more relaxed. We are on the 5-30-05 Harmony sailing to Alaska.
