We assume that I have an unlimited amount of money :)

I would rent a big house on the beach and would invite my family and all my friends from all over the world (also some of my virtual friends) who are dear to me. There would be lots of good food, drinks and music. We would talk, sing, dance or whatsoever the whole day (of course it would be a wonderful sunny day) and night - and then I would go.

Oh, what a wonderful way to go, unfortunately that does not even happen in fairy tales :)

everyone  nearly write that i meet my relates and i meet  my the best friends. i want to say them i love you"... but i think that you dont need last day to do that. you can do it everytime 

I have two answers. The first one is funny and the second answer is serious.

1... I would pay all my bills and debts because I don't want to die with a guilty mind :)

2... I would tell everyone I saw that I love them and they should not be sad.

I would like to spend it with my family and my best friend :)

then I would like to go for a long walk beside the seaside listening to my favourite music :)  

I would eat all my favorite things like baked ziti, foccaccia, milk chocolate with nuts or raisins, and my favorite French pastry, a Napoleon.

Then I would lay in my lounge chair, put on my Beatles, Stones, Guns N Roses, Bruce Springsteen, Bob Dylan, etc cds and wait to to go on to glory !
