Here’s the story on bus transportation at WDW; there isn’t a bus route at WDW that doesn’t have a glitch now and then. OKW transportation is no worse than any other route. In many ways, it’s better, because it doesn’t share with any other resorts. No matter which resort you’re at, you’ll find posts complaining about the transportation. We have stayed at OKW at least a dozen times, and I can count on one hand how many times we’ve had problems. WDW is a huge place, people are eager to get to parks and resorts, so if something goes wrong in their plans, you hear about it. Two hours to get to your destination? Uh - no. That would be a SLIGHT exaggeration, unless there was an accident or unforseen circumstances. Generally allow yourself an hour. It takes approximately 15 minutes for the buses to circumnavigate the resort (there are 5 stops); once it leaves the property, depending on the park you are going to, it will take probably another 20 minutes (that is to the MK or AK). You will have to add some time if you have an ADR at a resort. For instance; if you are going to the Grand Floridian, Poly or Contemporary you will have to take a bus to the MK and then board the monorail (in the case of the Contemporary you would just have a short walk after getting off the bus).
What I guess I’m trying to say is don’t worry about it; you will, during your stay, probably wait longer for a bus than you thought (and this could happen at any resort or park), but it isn’t going to ruin your holiday and restaurants won’t cancel you ADR if you are 15 minutes late.
