The buses are POP are really quite good.

Huh? - we stayed in Jan- walked past the UNBELIEVABLE bus lines daily- stood in line for almost an hour at DTD while other buses came and went.... decided NEVER again.
Ok..donning flame suit.....

seriously,I know lots of folks like it there,but sounds like OP is looking for some relaxing resort time,and POP isn't it.....
No flaming from me...it's all about everyone's personal experiences and perceptions.
Bus service to and from DTD is always the worst of any park. I had a car for the first time in Jan and found that it was very nice to just drive to DTD from BW...who knew it was so quick?? Granted, I drove there in the morning when it wasn't overly busy.
But the buses at POP really are not all that awful. Because there are so many guests there, the buses tend to come more frequently. I know that on one trip, my dd, dh and I had walked to the bus stop to go to MK, at about 9:00 am. When I got there, I realized I had forgotten something in the room. The bus was just pulling up, I told dd and dh I would meet them in MK, and I rushed off to the room. Now, my room was about a 7-8 mins walk from the bus stop...in the 80's bldg, back side, by the Rubic's Cube closest to the lake. By the time I had gone to the room and returned to the bus stop, there was another bus just heading in....not bad at all. Considering that I ran most of the way, I figure it took me about 13 mins to get to the room and back to the bus stop.
I have not yet seen huge lines at POP, and I was there in mid-Jan. But, again, I may have just been lucky. But most people seem to think the bus service at POP compares quite favorably with the other resort buses.
