My hubby and I just got back from our cruise today and yes we did the zip line in Belize....You get your moneys worth !!! The one we went on had 5 zip lines and 2 straight down repels....all over the top of the rainforest!!! Very fun!! The only crappy part is the 1 1/2 hour bus ride to get there, but it is well worth it in the long run!! Once in a life time experience!! We loved it!! Be careful tho, because there was another excrusion the was a combo of zipline and snorking. We did not do that combo one because that only had 1 zip line and your done.
