I don't know anything about the hotel, but here are some of my suggestions for what you can do while you are here:
Rent a car and drive a bit around the island. Go to Artenara and Tejeda up in the mountains. Or Teror, Arucas, Puerto de las Nieves, Pinos de GÃƒÆ’Ã‚Â¡ldar etc in the north.
Visit Las Palmas; go to the beach of Las Canteras, shop in Vegueta and visit the museums and look at the old buildings in Vegueta.
In the south you should visit Puerto de Mogan, Mogan and Fataga. There are lots of beautiful and interesting places to go on the island. If you don't want to rent a car there are organized tours as well.
Enjoy your holiday!
