I just did a search on the internet and came up with Traveling Baby.

It is best to call and ask, but are you planning to pick up a rental car?
The FAQs/questions says this:
Airports - Depending on your destination, airport service can be arranged in several different ways. With the exception of full-size cribs, items can be delivered to you directly at the same time you are picking up your rental vehicle or exiting the baggage claim area. Some locations also offer service to cell phone lots at the airport. All you need to do is provide your flight and car rental information on your reservation form along with an estimated time of arrival and departure. If you are not renting a vehicle and need service to your baggage claim area or cell phone lot please specify that in the “Special Instructions” section of your reservation form. To see what airport delivery options are available in your city please go to our
Location chart.
EDITED TO ADD: I did a quick check for Anaheim and it doesn't look like they do deliveries to airports.
Also, wouldn't you still have to go to the hotel to drop off your luggage?
The reason why a company has it at the Orlando airport is because WDW no longer allows companies to drop off strollers, etc. They have one specific company that can store their strollers on property.
Found this one that delivers to SNA:
