We stayed at Pop last fall. Things I suggest....a throw away cooler to keep small things cool. I am not willing to pay the extra to have the fridge in my room so this would work out better. It also helps if you have a rental car and can get to store, you can save a ton of money buying larger packs of snacks instead of paying Disney prices for single servings....though they do have some bigger package things.
Be sure to tell mousekeeping if there is a special event you are traveling for. My son got a birthday card and balloons from Chip N' Dale last year, it made his day. They definitely will go out of their way to make things special for you.
Love the frozen coke! My son loves it too!! This is probably his most favorite thing about Pop.
Get the refillable mug. Though our walk to the food court was a ways, it still worked out. I would fill it in the morning before heading to the parks and then fill it up again when we got home. Of course, I didn't like carrying it around so I didn't take it everyday but it worked out nice the days I did.... We didn't spend much time at the pool but I bet it would come in handy if you spent a day swimming or just hanging out at the resort.
And I save the best tip for last...................drum roll please............
Whatever you do, never, ever, ever shut your finger in the bathroom door. It hurts very, very badly. I know you may be thinking it sounds like a good idea but I am telling you from my own experience, DON'T DO IT! Really, it hurts, you will be sad, and a tear very well could start to form in your eye. Not to mention, if you do shut your finger in the door, the ice machine closest to your room will not be working at that time. So, if you still want to do it, even after reading this....go to someone else's room and make sure the nearest ice machine is in working order.
