Which agency to choose for an excursion to Tenerife?

Tenerife is my dream, I have wanted to go there for a long time. But I want variety, not the usual standard excursions - to try new dishes, taste interesting wines, see whales and dolphins. Has anyone used GetExperience https://getexperience.com/spain in Tenerife? Is it true that their water excursion takes place on a ship called Peter Pan?
