That is really up to you and where you will spend most of your time while in the parks. I personally LOVE POFQ because the dining and pool is pretty close to all of the rooms. Really, it is difficult to answer your question because I don't know what room you will get. Are all the rooms closer to dining and the pool at WL than POFQ? No, it depends on what room you get. Overall, POFQ is smaller so the chances of you being closer to dining and the pool is greater than at WL, which is larger.
I have actually stayed at both resorts. It is a nice benefit to take the boat over to MK especially with little ones. At POFQ, the only method of transportation is buses except there is a boat to DTD. It is up to you to figure what benefit is more important to you.
