How about a Mexican theme- mariachi music, Mexican food and decorations.
Or Jamaican- same elements
Basically I'm trying to plan what I should do for my 18th, the main idea I have is it to be in a bar as a few of my friends have done that in the past and it was good and my parents own a bar which is convienent.
Only problem is that a few people will be 17 still as I am the oldest in my year but a lot of my friends are older so there will only be a handful of 17 year olds. when my friend hired a bar out for her birthday there were a few 17 year olds but there wasnt really a problem. I also want to do a sort of theme so its not just a regular party i was thinking casino but not too sure.
