This reminds me of a true and funny story. A few years ago we were staying at Paradise Pier and DH was awake early and woke me to say he was going downstairs for "coffee and toast". Well, he stumbled into the Minnie & Friends character breakfast. He came back to the room all happy and chipper stating "Wow, Minnie sat on my lap, gave me a kiss, a lot of other characters stopped by to say hi, waved and it was a whole lot of fun!" He did eat a full plate of food and was surprised at his $20 bill, but said it was quite fun and he had no regrets.
So there you go, adults do go by themselves to a character meal
