It has its pros and cons, and it depends on your employer. Your employer generally has to approve PTO even on a PTO plan that tracks hours. If you don't trust your employer to honor a reasonable PTO policy - unlimited or otherwise - then you should get a new job because there's probably lots of other problems. I've been able to take blocks as long a 3 weeks off at an employer with an unlimited PTO policy, because I worked hard when I was there and my manager and I were on the same page. I told them when I was going and how long for, and they said nice, have fun. Etiquette was to give at least 2x as much notice as the duration of the PTO. If you're going to take 3 weeks off give at least 6 weeks notice.
