No one can say for sure. It's one of those "You'll know when you get there" issues. People can chime in with their experiences here but they'll have no bearing on your ability to cope. I'm not even sure that previous experience is a surefire indicator. After multiple trips to La Paz (12,000) and Cusco (10,500), some have gone well for me and others have not. I don't think I've ever suffered from actual AMS, but I've had trips where the acclimatisation took a lot longer than others. I'd love to visit Tibet one day. The same concern has kept me from doing it.
