What is jury duty like?

I got a letter in the mail being called back for jury duty, the first letter I got was almost a year ago and I opted out due to a family vacation, and I am being summoned to go now, I'm 19. I live in Missouri in the Kansas City area, and the I am being called in to serve on the 20th of this month. I am curious of what it is like to serve as a juror, I heard that you get to stay in really nice hotels, during the time you spend, and I was told you get 60 dollars a day for compensation and meals are paid for.
