If you were me, would you go on this trip or not?

Knowing about Aaliyah and her spirit, she wouldn't want for you to spend excessive monies that you can't afford right now. However, she is worth your time and effort. Now, if next year, you decide to go to some affair or another birthday vigil of hers, then you will have saved the money. Don't stress yourself out. I wish you well. Peace, Love and God Bless.
