I don't think most would argue with that.

I've been staying at one of the on-site hotels a couple of times a year for more than a decade now and I have never paid that much per night. It all depends on when you want to go and how well you pre-plan.

I have a trip coming up in April. I have 4 nights for $179/night. Yeah, I could get cheaper off-site. Actually, the on-site Cabana Bay hotel has very reasonable rates too (around $109/night). You don't get the Unlimited Express Pass, but you do get the early access every morning and free transportation to/from the parks and City Walk.
