Horseback riding

[Mallefiscent]

My friend has booked a carnival cruise for March and wanted to go horseback riding in the ocean.  The cruiseline's shore excursion is already booked.  Can anyone recommend another company?

If you go to Beach area on the left, there are plenty of water sport activities.  Horseback riding was one that I saw.  

 

The beach was crowded, so it was more of a lady on the horse with the guide walking alongside in the sand.  I did not actually see them get into the ocean.
