I've been looking since yesterday. The only place I've seen with a better price is AAA. I've checked expedia, priceline, etc... and they're either the same as the Universal's site or more. Then again, I'm booking for an onsite for this October.
I saved almost $30/night by booking through the Loews hotel site directly.
I would have thought they would be the same as Universal's, but the best I could get for HRH in the middle of Dec. was $192. The same room on loewshotels.com was $164. Never stop poking around, you never know what you might find.
