$3000 to spend today.
I think I’ll take a trip this time. I had a chance to go to Hawaii back when I was in high school, but I didn’t go because the dates my parents picked were when school would be starting and I didn’t want to make up all the work (since I’ve gone through that before when we first moved to our house when I was starting jr high). So since I’ve never been to Hawaii, I’ll book a vacation package for two (haven’t decided who will come with me yet – post a comment if you want me ot take you) for a 5-night stay during my birthday. 
The Outrigger Waikiki On The Beach looks like a nice place to stay.
After booking the vacation package (flight, hotel, and car), there’s about $700 left for spending while there (for food, shopping, and whatnot).
