POP to Legoland is about $36 for X. With just about any Disney resort, you have to enter it as Disney's _____ resort, as in Disney's POP. If you do that, it "pops" right up.
(I have to stop using RideGuru for Orlando fares. Every time I do, I'm still shocked at how low the driver rates are there. On that POP-Legoland ride, an Orlando driver would make a full $10 less than I'd make for the same ride here in Miami! SMH.)
