YS is quite a bit farther away but if you don't mind that , it is more scenic and having steps with railings, easier to access. There are so many things to see and do on your route. I'm not a fan of the Appleton Estates tour but there is something called Apple Valley, a sort of a Jamaican family orientated park that your children would enjoy. Middle Quarters and Scott's Cove specialize is some unique foods such as Peppa Swimps (hot, hot, hot) and fry fish and bammy. Sure you can get it in Negril but just like you'll never experience jerk like what you get in Boston Beach, the fry fish here is unique. Here's a little on YS. http://www.discoverjamaica.com/wheretogo/index.html
