The OP has probably gone by this point, but given that this thread's been bumped:
I've stayed at Worldmark several times, and I just take the ART buses over. There's a pick-up area right in front of the parking garage. I'll grant that neither the app (A-Way We Go) nor the website (
www.rideart.org) are the most intuitive in the world (both used to be better), and the exact route that goes to Worldmark has changed several times over the years. HOWEVER, given that it's about $25 for a five day pass, it's the most economical option. By comparison, those Uber rides add up.
The buses run from ~an hour before park open, with the last bus of the night headed back from
Disneyland about 30 minutes after the last park closes. Additionally, there is real-time bus tracking on the app AND at the moment, there are actually two different ART routes that go back to the resort, so you have more options than many other nearby lodgings.
There was a time in the reopening period that lasted until relatively recently where the shuttles were only running by request in the middle of the day, but that has ended and they are back running every 20 minutes or so continuously.
I've also Ubered over before, especially if I'm going directly to one of the Disney hotels or DTD, but depending on timing of the busses and/or your Uber driver, an ART bus could well show up at Worldmark before your Uber gets there, especially with two routes stopping there. The DL Uber pickup area is also a mess at park closing time, so while the last ART bus back is always packed, it's not necessarily any less chaotic to go over to the normal rideshare area and taking an Uber back-it'll take awhile for your driver to get into and out of that area that time of night, and there will be plenty of guests and other drivers around you trying to do the same thing.
I've never gone over through the Toy Story lot and gotten on a bus there from Worldmark. While there's always a steady stream of TSL busses, those are also ART busses contracted to run for Disney, so in my head, that's walking further to get on an ART bus vs. the closer one I could use from Worldmark. The walk from Worldmark isn't horrifically far, but it's longer than most people would want to do every day, especially later in the day when you head back.
TL;DR: Just take ART. It's not perfect, but it's the best overall option IMO.
-- Our prior go to off site was Hyatt Place. It's now Hyatt House for the walk vs ToyStory option.
