When you check in they will give you a “bus” map that is color coded. I tried to find one online for you yesterday, but I could only find ones without the bus routes. There are 3 bus routes, I believe they are purple, yellow and orange. Purple, I believe, is the fastest way to get from the outpost depot to settlement depot (pioneer hall, marina). Each color bus runs about a 1/3 of the park. It sounds really confusing, but it isn’t- plus there is a big color coded map at each bus stop.
The internal buses seem to run pretty efficiently, but the external buses are always hit and miss no matter which resort you stay at.
Have a great time on your trip- maybe we will run in to you!!:laugh:
