Depends what music you like.
Day time for me is..
Chill at the beach round the pool all day really
Go Mambos about 8 for the sunset, something to eat after that.
Go home get changed and then hit some bars, the west end is cheap I dont mind it though.
Bar M and the Orange Corner are personal faves too.
Club wise as its ur 1st time you have to
Go Manumission @ Privledge on a Friday, 10,000 clubbers and a amazing club.
Cream @ Amnesia as such a good atmosphere
Being young I think you would love Judgement Sundays @ Eden
And for a top atmosphere and loads of women around you go to Hed Kandi @ El Divino on a Saturday.
Money wise I would say about £100 a day, but some people spend less, most spend more!
Hope that helps
