We stayed at the Swan last in 2021 (before G+) and it had great wifi, but the amount of guests were limited so I question the actual saturation of the network.WDW wifi is weak when you need it.
Plus 100's of other gst are using also.
This! I found that, weirdly enough, if I stood facing the wall near the hanging ironing board at All Star Music I had some of the best service!Cell data. You might have to go outside to get the best speed.
Don't laugh.... I have sometimes found the highest data speeds to be in the Disney resort room's restroom. My friend has also tried this and experienced the same. I have scored Rise, Remy, and GOTG hanging out by my shower. haha
