Does Disney give you free unlimited express passes to every ride when you stay onsite? Does Disney give you a rewards program that entitles you to free upgrades including suites? Does Disney offer a two year annual pass for $189 renewable at $99/year? Does Disney offer you a 7 day pass for $87? Can you stay at a deluxe hotel for $149 at Disney World?
Walt Disney World charges you an extra $10 to be dropped off by taxi at the parks to try to make people stay onsite. I've been charged. Universal lets you be dropped off for nothing.
If those things don't more than make up for the parking fee, then I don't think anything can satisfy you. There are many other hotels in the Universal area an dbeyond that also charge for parking. Swan and Dolphin, Renaissance Hotel at Seaworld, Nickelodeon Hotel, Gaylord Palms, World Center Marriott, Crowne Plaza are just a few.
Disneyland also charges a resort fee as they are in a similar limited parking area. I don't hear any complaints about it and their rooms are much more expensive than Universal's.
The Loews parking fee isn't going to change but Universal itself does a great job in more than making up for it.
