We are going on NCL. Debating on doing the Damajagua falls excursion with only waterfalls and no zip line. After reading a lot of posts and comments I am kind of nervous for it. We are a group in our twenties and aren’t a particularly athletic group. Can we do this or is it going to be too physically exerting? We don’t mind a little challenge, but it’s a vacation and we want to all enjoy our time.
