Disney World used to do this too precovid, called Magical Express (when staying in a Disney resort). But it was even better because they would grab your bags straight from the plane, and it would be in your hotel room waiting for you before you got there. So you wouldn't need to do anything at all, except get yourself to Disney using the chartered bus that dropped you off at your hotel.
They stopped doing it probably because of covid transfer fears, but probably more largely because attendance was down, so it probably wasn't cost effective. They've kept the chartered bus service, but removed the "magical" parts of it, so now you have to get your own bags again.
The Disney travel agent told me to print these labels out in Australia and just attach them to the luggage. Then we just had to hop on a bus when we landed in Florida.
Shame they don't do this anymore by the sounds of it. I was completely sceptical of the whole Disney experience but it all went so smoothly.
