As a matter of fact most new ships have safes right in the cabin with instructions on how to use them. As a rule of thumb, wheel chairs are available for passengers who are injured after they get on board. Most suggest that you bring your own collapsible one if you will need it throughout the cruise. Holland America Line has in the past provided a wheel chair throughout the cruise if it is requested in writing 30 days prior to departure. Check with your agent when booking regarding your ship's policy on providing wheelchairs to passengers.
Most ships have a daily newsletter with news, headlines, selected stock quotes and sports scores.
Staterooms on many ships are even equipped with televisions. While many ships now have telephones in passenger cabins, you can also call someone on shore through the ship's radio operator while at sea. And, you can make phone calls from most ports. In addition, many ships have fax capabilities. Almost all cruise ships have laundry facilities and a great many provide dry-cleaning services.
