We did not go to Gibraltar , but from the beach i thought i saw a dolphin jump, and i was right, way way in the distance, but have around 5 pictures of it jumping out of the sea.
Pueto Banus is not my cup of tea , so over rated in my eyes yes a beautiful place at night to see and be seen , there was so many boats there for sale and there was some beautiful old wooden sail boats plus there was a beautiful original fiat 500 parked along the front too.
I took Emma there mid morning and it was cold too so we did not stay long, infact we stayed for about 2-3 hours and that cost us over 10 euros
