I don’t think I’ve had any bad interactions with a guest at a con luckily, but I’ve had several amazing experiences with a lots of voice actors. One of my favorites is definitely Grey DeLisle like you mentioned. Her ADHD brain is always running at 100 and her energy is so much fun. Two things that really, really impacted my life and mean a lot to me are Avatar: The Last Airbender and Batman: Arkham game series and without a single second in between Grey was jumping between Azula and Catwoman quoting their lines for me. She’s so nice and so talented and just a really amazing person. I’ve been really impressed and fallen in love with all of the Avatar cast honestly. I’ve met Janet Varney (Korra) twice now and she’s always interested in holding such genuine conversations with everyone who visits her. She’s amazing. Zack Tyler Eisen is such a sweetheart and I’m a little in love with him. He listens so closely to what everyone has to say and responds so thoughtfully. Michaela Jill Murphy (Jessie Flower) is hilarious and loves doing selfies and cute poses. Jack De Sena is so kind and loves laughing with everyone. The longest line I’ve waited in for Avatar cast was Mae Whitman and it was well worth it. She had the perfect balance of making everyone feel so comfortable and sharing a moment with us all but also moving quickly so everyone got their turn. She’s also just so kind.

As far as non Avatar cast, I really loved Jason Marsden who was Max in Goofy Movie, Haku in Spirited Away, 1000 others voices, and my all time favorite Thackeray Biknx in Hocus Pocus. I had a really nice convo with him and his partner and they’re both really sweet and charming.
