My wife and I have been to Jamaica 10 times and have exhausted many of the excursions, etc. We are excited to return in March for our third time to Couples and our first time at CSS. My wife has a form of Rheumatism causing her to have weakness in her arms and hands. She would love to try Zip Lining but we wonder if she will have sufficient strength. Those of you who have zip lined, do you feel that signifacant strength is required in your hands and arms? Just an opinion will help to guide us. Thanks in advance.
