Its really all according to what you are looking for Bernie, I have been to all the Canary Islands. Tenerife does have everything, the South of the island is livelier, the North is more Spanish and greener, most of any action takes place in the hotels. Theres no proper beaches on Tenerife, the sand is black or imported, bearing in mind the island is volcanic. The reason I mentioned Fuerteventura is because Ive been back to the resort of Caleta de la Fueste (also known by several other names) its only 15 mins. from the airport, very flat to enjoy long walks. There are quite a lot of nice bars and entertainment in the evening, not 18-30 age group but a good mix of ages. There is a very nice sandy beach that becomes quite deserted as you leave the resort, camels lay about on the sand, small cuddly creatures live on the rocks and come up to the tourists to be fed fruit and nuts. I do feel that the resort has something for everyone and the weather is usually around 23-30 degrees.
