We did stay at GDT a week ago, I spoke to the hostess and she said almost everyday for the two weeks we were there they were on a hour and a half wait by 5:00. Plus, unless you are at the resort you can't join the list on your phone. We would come back to the park at 9 or so and they were still on an hour plus wait.
The issue is everyone is eating at the same time and the restaurants owned by WDW are at about half capacity. There is less supply and more demand.
The DS restaurants are filling their tables per Florida directives, not WDW's.
With the Maya and Toledo closed it leaves only Rix Sports Bar, 3 Bridges and the CS for the entire complex. The Parks close early outside of EPCOT... So DS gets packed at night and so do the few restaurants open at the resorts. Heck, Rix was running out of reservations when we were there, that never happened in previous years.
They were taking To Go Orders from 3 Bridges on the app, so we did do that a couple of nights and just sat at tables overlooking the lake outside. The food was still better than eating CS, but wasn't the same as having a TS meal. Ha Even those To Go slots would be pushed to 10pm by 7pm or so.
This may all change in the next few months, but WDW continues to be slow to let up on their self imposed restrictions regardless of directives and evidence that those restrictions do little to nothing other than cost them money.
