I would imagine you can go to any of them.

They don't mind so long as you buy a few drinks.

We always go into the Barcelo Hotel. The in house stuff is pretty poor, but the Beatles tribute, Beijing acrobats etc are all very good.

thanks lewiston for your reply

The Barcelo is a nice hotel to go in for a drink and watch the show.
We have just returned from Caleta and didn't bother with any hotel entertainment - we went in Piero's most nights, the shows there are good, particularly the Aladdin Show, Hypnosis Show and Guitar Heroes Tribute Show.
The Dome has some good shows too, and I heard the entertainment at The Kings Arms is okay
This site HERE has a good guide to bars and restaurants in Caleta.

We have just returned from the Barcelo Fuerteventura and thought that the standard of the visiting acts was very good (Black brothers, The Gauchos), the in house stuff was ok, they mime to backing tracks most of the time, re Lion King which the kids enjoyed and they do a mini disco for younger kids (up to age 9 maybe) which the young ones seemed to love.
