I'm interested to know which park my teen would enjoy spending more time in-disney or universal? I have 6 days. Also, what tickets do I buy if i want to leave for lunch or take a nap and be able to get back in? Do they stamp your hand like they do at other parks? 


, I'd suggest you purchase/borrow a guide-book for the Orlando area and get acquainted with the different WDW & US/IOA parks before making a decision. Also visit this board often, often, often. If your teen hasn't been to any of these parks, I really don't think you can wrong - there's SO much that each park offers.
