What Was Your Best Low Cost/Free- High Yield Vacation/Adventure ?

I have been in Kenia and a friend booked a Safari for us even though I wanted to go to Mombasa. Turns out since she is Kenian it was about 200 Dollars. It was in a tent with propper beds and cupboards. A Living Room Tent , a Dining Room with Waiters and Cook. We were the only ones booked. Means we could ask the Driver anytime to go out and explore. We saw amazing Wildlife. It was the most amazing thing ever.
