In the last 8 yrs, we have been to WDW 7 times. 5 at Pop, once at ASMusic and last month at CBR. We liked Pop because of the fun atmosphere and the food court (love the Beef and Blue Sandwich). The bus stop wasn't that much of a walk once you learn the lay out of the land and how to cut through areas. As posted earlier, there were a lot of strollers and big carts. It wasn't unusual to have up to 3-4 electric carts waiting in line which backed up others loading on due to all family members entering with the cart ahead of the line. (I'm not bashing those needing carts, I'm just giving MY experiences) I will say that when lines back up too long, they do send extra busses which is really nice at the end of the day when you have 3 or 4 loads of people waiting to get back to the resort. What I found interesting is that we excepted the behavior of the guests from Pop on the busses to be normal, (parents letting kids larger than lap sitting size to take up seats while elderly and parents carrying sleeping children had to stand) but every bus trip from CBR was quiet, calm and people were polite and offered seats to those needing them more. I don't know if it was unusual but we never waited more then 10 minutes for a bus and we always got one the first bus (only had to stand one time all week). That being said, we didn't really take advantage of any extras at the moderate. For me, I prefer Pop at less $ so I can stay longer but my DW likes to less crowded busses and quieter layout of the moderate resort. One last thing, we used the refillable mugs everyday at Pop and found it not worth the bother at CBR.
