We just got back and my kids were 5 and 3. I also debated poly, cr, and beach club. We could afford to stay there, but I just could not justify the cost. It was almost double the cost of POFQ. We booked there and then received and amazing discount to stay at AKL. One reason I picked POFQ is because they just built a kiddie splash pad with a small slide that my kids would have loved.
We took the monerail to CR and poly for meals and the convience is definitely there. It is a quick ride to poly and CR and the kids did not need to get out of the stroller so you would not have to wake a sleeping child. However, you need to decide if that is worth the extra money.
My experience is that we went to the park in the morning and stayed until the kids were tired, around 7-8pm and then headed back. I feel it would have been crazy to take a mid day break because with waiting for the bus and driving, the travel time could be around 30-40 minutes. We never waited more then 15 minutes for a bus, but we were also a 20 minute ride from our hotel to MK. My kids also do not nap. If they did, I would have tried having them nap in the stroller. This worked with my youngest when we were at a local amusement park.
We rented a city mini double and it folded easily. My DH did not have any problems carrying it onto the bus. There were several nights that our kids fell asleep on the bus and when this happened, DH quickly jumped off to open the stroller and then came back on and we each carried a sleeping child to the stroller. They were so tired they stayed asleep during the transfer.
