I don't know the answer to your question, but wanted to post our experience.
We have done two Land-and-Sea trips, staying at the Poly both times. On both occasions, we were placed in Tokelou. My guess is that, because so many land-and-sea packages include transfers, they group everyone together for the purpose of luggage collection on your day to the port.
If you end up in Tokelou you will love it. Both times we were in a garden view room facing the quiet pool. On our second trip, we were closer to the lagoon, and could see part of the EWP as it went by, but it was so easy to run out to the beach to watch.
I have heard that any building at the Poly is great, so relax and enjoy! We are going to WDW in October, and decided to stay at the Ft. Wilderness cabins. This is a big change for us and I heard the resort is very fun. However, no matter how much fun I am having, I think we will miss the Poly.
Have fun!
