The past few days, I have had to wait upwards of 20 minutes ("We're almost in orbit...") to view/modify a resort reservation. Is there a problem with the site? That's pretty ridiculous to have to wait that long online. Is this unusual?
No, but I doubt it's the browser when the software shows the approximate wait time for MDE to respond. If it knows you're waiting 20 minutes, a different browser wouldn't likely make a difference.
I’d at least partially blame SWGE, honestly. This has been the worst the MDE app (and the regular site when I’ve tried as a backup) has worked for me in years of visiting WDW. Disney IT is really demonstrating its unfitness in early 2020.
The question has to do with viewing/modifying a resort reservation, which is more of a Resorts Board topic than a Theme Parks Attractions and Strategies topic.
The online “queue” usually happens around high resort reservation website traffic times, such as when promotions come out, free dining comes out (like what came out yesterday), etc. It’s what they use to throttle web traffic to, in theory, make it more usable to make or modify reservations when you do get in.
