Just got back last night.
Bus service was outstanding. Never waited more than five minutes, with only one exception (about 15 to DTD @5:30 Friday). Out of six days, with no rental car and relying completely on Disney bus transportation, with ONE SINGLE wait of more than five minutes, I was more than thrilled. We had more than one occasion when we had to stand, or there were others standing. However, Pop is so centrally located to everything that it wasn't a big deal at all.
Everything was clean, clean, clean. All Pop CM's were very pleasant and helpful. Not a single complaint about the place.
