Depends on what you want to spend really. Myself, wife & 2 teenagers went in August, ate out most nights, usually nice meal, drinks and a couple of deserts would be around the £30 -£35 mark. If I were you i'd take a debit card and use the cashpoints in town. Taxis are cheap but aggree a price first. Be acreful initially in the shops as a lot of items aren't priced and the shopkeepers will assess how much they think they can get away with charging you!!
