My wife and I went to Ocho Rios Sandals for our honeymoon. It was an all inclusive bit. We tipped sparingly, but didn't carry cash around the resort if we didn't have to. This was our first trip to Jamaica so we wanted to do the experience things.
We were busy doing something every day and by the end of the trip we were tired and felt like we hadn't relaxed at all. My advice would be for a week long trip, plan 3 days of activities and then just relax on the other 4 days. Like an every other day thing. Also, if you don't make reservations or anything in advance, you don't feel like you need to do it. You can just wake up one day and decide to do something if you want.
