Sorry if this has already been posted, but, I had debated this very same thing myself! Last year, we stayed in a preferred room at Pop, because a family member we were traveling with has some hip/walking issues, so it was really necessary. Of course, we were right across from the Hippy Dippy Pool, and it was very loud at night.
That being said, I have a hard time spending anywhere upwards of $500 more for a vacation that is, for us, going to be essentially the same, just in a different room. Since we have DS3, the theming of the Pop is more to our taste for his enjoyment. When he's older, I'm hoping to move up into one of the mods, when the distance between things won't be such an issue, and perhaps I'll be looking for more relaxing/down time.
That being said, I've read a lot of threads, and the main Pop FAQ thread about where people stay when they want a quieter room. The general consensus is to request something on the fourth floor, lakeside. This will ensure that you are not facing a pool, and no one will be walking above, which should help eliminate some of the noise issues. I would recommend searching for a map of the Pop resort, so you can possibly pick a building. I've noticed a lot of DISers put in room requests when they make their reservations, and also fax them to the room assignor three days prior to their trip. There's a sample fax in that thread also, I believe. HTH!
