From what I've read, the Flamingo Crossings hotels (Western Way) are pretty much all that's currently at that location. That may be a pro or con, depending on your point of view. But, it's important to realize that they are on State Road 429, which is a toll road. That's less of an issue if you are driving your own car. But, some rental car companies charge large amounts for the privilege of paying tolls.
Personally, unless I got an amazing deal, I'd remove Flamingo Crossings from your list. It's really on the opposite side of where you're going.
As for traffic in general, it's not ever horrible (to me). It's mostly just normal major metropolitan area congestion. If you go to Bing Maps or Google Maps, you can customize your results by changing the "leave now" setting to a specific date and time of day. The sites will use historical traffic information to provide a time that includes traffic.
For example, here's the trip from the Residence Inn on Marabella Palm Court to the Disney Springs parking ramp leaving at 5:30pm on a Friday night. As you see, they only add about 1 minute due to traffic.

The trip from the Residence Inn by Sea World (11000 Westwood Boulevard Orlando) is similar. It says 9 minutes normally, but 10 minutes when you factor in traffic. (Link to that map:
