The Telegraph listed the top 50 cruise excursions that "you would struggle to do alone or which could be difficult or expensive to organize". Three from the list are offered by Royal Caribbean.
19. Horseback ride and swim, Jamaica
The fun starts after a rather tame ride, when you change into a swimming costume and remount the horse, now bareback, for the swim. The horses really do swim; you have to hang on to stop floating away. £68 for three and a half hours.
20. Amazing secret river, Cozumel
Join a guide for an exploration of a subterranean world filled with stalactites and stalagmites. You'll walk, wade or swim around the 600-metre route. £62 for eight hours. Minimum age six.
46. Elephant safari ride, Bali
You'll be taken to the Elephant Safari Park at Taro for a ride through the forest on one of these gentle giants. The tour ends with a splash at the park's bathing lake. £84 for about seven and a half hours.
