[QUOTE='rach [shikari];38144745']780 should be more than enough and you'll be able to do the waterpark and hire quads too if you wanted.
Foodwise, depends what you want to eat. A lot of restaurants do set meals for about 10 euro or theres places like maccies/pizza hut (buffet) if you preffered.
Pre drink if you can, theres a place called incredible universe that does cheap crates, but all the other supermarkets do dead cheap vodka and stuff too.
Bars on the strip are pretty much all the same price, 5 euro a drink and 3 per shot, though the PR's will try to do deals with you. Try to haggle with them if you can as they'l give you BOGOF with about 4 free shots each, so deffo don't go in without a PR.
Club drinks are about 7 euro a drink and don't tend to have any offers on. I have no idea about entry prices as I have never paid as I had a workers card.
Someone mentioned above about Black and white club, unless your really into rap/ r&b avoid this club, its not very big, full of people who think they are it and they are the worst place for watering drinks down.
Go to Castle for your house music, its huge. Go to club ice for the foam party on a monday.
There are also two after clubs, River Reggae and Aqua, both with pools and open till 7am if you really wanted to party hard!
Have a great time, wish I was going back this summer, been 3 times, epic!
Black and White worst place for watering drinks down? I found the opposite, its the only place you can get a proper drink. BnW and Club Ice are owned by the same guy btw..
