We're first-timers cruising on the Norwegian Sun 1/25/08 (anyone going?) and we're pretty sure we want to do a horseback tour in Cozumel. I'm not sure we really want to be locked in, though. We'd probably like to do an independent tour so we can save a little fundage. Are we stupid to wait 'til we get there to arrange it? Can anyone recommend a decent company to go with? Is the tour through the jungle cool? Thanks for sharing your abundant wisdom!
