Well hello there Emily, and welcome back to planDisney!
Here at planDisney, as we collect data and do our research at Disney Destinations around the world we sometimes find ourselves similarly in search of key quiet spots to attend meetings or complete calls online, or compose the content that we write for Disney guests every week. I wish we knew
which Disney Resort Hotel you'll be staying at soon, so feel free to
come back to planDisney to let me know for more specific suggestions but here are some of my personal favorite spots that I can share in the meantime:
I think that it's always handy to ask the helpful Cast Members when you arrive if they have a quiet spot that they're willing to share, and sometimes this has resulted in some very special finds that other guests may not know about! (It doesn't sound like you're aiming to get any work done from within any of the theme parks, and finding serene spaces to do so can be challenging but not altogether impossible!) I hope this helps a bit for now, but as I mentioned - you're always welcome to come back to planDisney if you'd like us to narrow down some recommended spots with a specific location or Disney Resort Hotel in mind!
Wishing you all the best in your quest for some quiet working space ahead of your upcoming stay!
Prince
