hey guys, i am planning a trip to europe next yr (i know its ages away but i have no idea what im doing). it is my first trip overseas and i am having some difficulty budgeting because i have family in a few countries. im planning to stay for about 5 months. i have family in italy, sweden, and denmark so accomodation in those countries will be fine. however id also really like to see spain, portugal, france and germany and spend some time partying in ibiza. i know i have alot of ground to cover, i have read a few of the posts about budgeting in europe however im still at a loss of how much i should be taking. im 18 this yr and for my birthday my parents are buying me my ticket (i know i am as shocked as u are ahaha i think they are just trying to get rid of me lol). so airfare is also excluded from my budget. after reading some of the posts on travelpunk i estimated about $12,000 aussie dollars for the 5 months. keeping in mind i have accomodation in some countries.

id appreciate any tips or advice you guys can give me even if it isnt just about how much $$$ to take and just about the countries themselves, as i said im brand new at this, its my first internetional trip and i am soooooo excited. the more info i can get the more organised ill be.
