Shouldn't admit this but if going to the Clube Praia da Oura in the Algarve register on their website
http://www.clubepraiadaoura.com/cpo/index_cpo.htm for the special offers and they send you an email asking for your address to send you a special voucher to spend at the hotel. I registered twice in my name and once in my Mrs name (3 different email addresses). The first time I received a voucher for €20 and the next 2 for €10 each, yes €40 in total which we spent in the restaurant for breakfast @ €5 per meal (early breakfast).
They had to be validated on arrival which was a bit embarrassing, but only for a few minutes or so

, but what the heck.
So if you are going to the Praia da Oura, a little money saving tip
