Mobility Equipment Guidance
Here are some important things to know about bringing a mobility device onboard.
If you will be using a mobility device or have special needs, we strongly recommend you travel with a person physically fit to assist with your needs both onboard and ashore.
Although we do not offer mobility devices onboard for personal use, you are welcome to bring your own device. Alternatively, we do partner with the following companies who provide wheelchairs and other medical equipment for rent, and they can deliver directly to the ship. If a rental is a better solution for you, please do contact them directly.
Special Needs at Sea: 800-513-4515 or 954-585-0575, or visit the Special Needs at Sea website
Scootaround: 888-441-7575 or 204-982-0657, or visit the Scootaround website
Please ensure that your mobility device meets the following specifications:
Maximum device width: 22” for standard staterooms, 31” for wheelchair-accessible staterooms
Maximum combined weight of the wheelchair, including guest: 600 pounds (weight may vary outside the United States)
Your mobility device must be securely stored in your stateroom when not in use. This will ensure that hallways and other public areas are clear for other guests and crew to safely move throughout the ship. We do not offer alternate locations for mobility device storage onboard. For assistance onboard with charging your equipment in your stateroom, please contact your stateroom attendant.
