I wouldn't depend on that site. I've found that it's pretty out of date. For instance, if you put in that you want to go from WL to MK, it spits out first the boat ride, and lists that as 13 minutes. I've taken that boat many, many times and never got there in close to 13 minutes. It's a nice ride, but takes longer than 13 minutes, even without adding wait times.
Also, that site mentions the WL bus stopping at the TTC, and then hopping on the monorail to get to MK. This simply is no longer true. WL has had direct bus service to MK now for probably a year or so now.
Finally, when looking at going from the Poly to EPCOT, it gives you 3 ways to get there, but neglects the easiest and fastest: walking next door to the TTC and catching the direct EPCOT monorail.
