We stayed at Pop in Sept - and it was me that did the runs to the machines, the food court and laundry - always by myself!!
We chose to spend the extra $10 for preferred, which is closer to everything - honestly - I always felt safe here - its well lit - and when we stayed till park closing, so did a whole bus full of families - all stop at the gift shop and the food court (lots of people remembered to keep their refillable mugs with them, not us - I'd go to our room, get the mugs, refill them, walk back)
If you're worried, say something to the CM at check in - you should be reassured... I dont think I'd want a ground floor, or a top floor... but that's just me!!
You'll be fine, I'm sure!
