My family and I are heading to WDW for Thanksgiving week. We love POTC and are looking forward to riding it as often as possible during our visit. I will be going in with the expectations that nothing will be different from previous trips other than a freshening up of costumes and animatronics. My guess is that a lot of the disappointment in the refurbs that has been reported to date is due to unrealistic expectations that significant new stuff was going to be added.
I consider the refurbs analogous to changing out old, dimming fluorescent light tubes before they completely burn out. All you're doing is replacing the old with newer versions of the same. While everything in the room may appear brighter and fresher due to new bulbs, nothing has really changed. You didn't rip out the old fluorescent fixture and replace it with a disco ball, laser lights, and a fog machine!!!
