Spending Money

Hi
Ive posted before regarding alocohol prices etc...but im just wondering how much spending money for the week would be enough. Im roughly bringing around 400-500 but im unsure as to whether or not that will b sufficient. My main concern is alcohol prices and Taxi's running after midnight. I've heard that purchasing alcohol at a shop and drinking it back at the apartments is a handy thing to do and can make the nightlife a bit cheaper. Also would it be a good idea to buy alcohol at duty free and bring that back to the apartment. Asking this on behalf of myself and a friend who will be going with family near the end of July....
Thanks.
