I'd respectfully disagree about the 1.5 hours, it really shouldn't take you that long unless you just have horrible luck with waiting for a boat or monorail. I've done the boat to MK then boat to WL, I don't remember how long it took but no way it was 1.5 hours. FWIW, if you are in a rush to get to WL you can always cab from Poly to WL and take the boat/boat or boat/monorail combo back. That plan works well for say, a dinner, where you can be on a more leisurely pace at the end of the evening.
