The Solarium on the Enchantment had "snacks" available in the late hours. Snacks were pizza, hot dogs, fruit, etc. I don't remember the exact hours, but I want to say it was something like 10 p.m. to 2 a.m. It was usually available after the Windjammer Cafe shut down for the night.
Other than the Solarium and room service, I really don't know what the late night options were. I had young children and we were always done for the day by 10 or 11 p.m.
There was the one midnight buffet night that was kind of fun to check out and test out!!!
