u can in most of them,it normaly costs around 7.50 euros.

there are spa supermarkets near most hotels on there parades,good selection aswell.

legends in costa stays open late but its not a nightcub,if u want a nightclub puerto del carmen is your best bet,but 30 euros in a cab so a bit pricey or go for the bus which is 2 euros,big difference but it takes 40 mins by bus.
