Don't worry! None of the rooms at WL are more than a few minutes walk from the pools. The standard rooms are the ones around the lobby. Think of WL at a U shape. The bottom of the U is where the lobby & standard rooms are. The main pool is in the center of the U. The boat dock is above the left long side of the U. The lake is at the top of the U. I'd say it's about a 5 minute (maybe less) walk from the lobby to the boat dock.
Enjoy the lodge! Be sure to check out the WL faq, part 5 post, page 1 for lots of great info!
