Robin answered your question, but I wanted to clarify that they're passes, not tickets, and are included on your Disney tickets. If you read through the FAQs in this thread, it'll explain more fully how you can use them: http://www.carolinah...-updated-71213/
We've done DisneyQuest and the water parks, and both are fun (lots of retro games like pac man and carnival games at DisneyQuest, and virtual reality games like the pirate game Robin described). Both can be full day, or half day, depending on how much you and the children enjoy them.
I've never done the golf yet - it's the first time they've been including on our tickets. I'm not sure we'll have time to do them this year, but hopefully others will and can give us some insight for next year.
