To be honest, the pool wasn't much to look at. It's just a regular, rectangle-shaped, concrete pool. No special landscaping or anything. I'm not sure about the lake, but it didn't look like it was anything special either. In fact, I don't think it could really be described as a lake at all. It looked more like a drainage pond to me. The hotel is on a really busy highway in an extremely developed commercial area, so there really aren't any "nice" views, in my opinion. Our room overlooked a pretty bustling stretch of Hwy192 and we actually did enjoy sitting out on our balcony watching the people walking up and down the strip, etc.
As I said before, the location is the really great thing about this particular hotel. You can take the back way into WDW without having to get on the interstate, which is nice. There are good sidewalks in that area, so it is easy to walk to shops, restaurants, etc. I don't know what else you have planned for your trip, but there are some fun places along the highway not far from your hotel - lots of neat miniature golf, go-carts, etc.
Also, you will be really close to the town of Celebration. Every night during the Christmas season, they have "snow" on Main Street. It happens every hour on the hour from 6p.m. to 11p.m. They have some really cute shops and restaurants, too. They also have horese-drawn carriage rides, strolling Christmas carolers, etc. It is nice to drive around Celebration and look at all the beautiful homes. They really go all-out decorating for the holidays. It would only be a few mintues drive from your hotel.
I'm sure you will enjoy your trip! Have fun!
