I'm sorry I do not know exactly when Sleepy Hollow is open. We went the week before the busy Christmas week and it was open, quite empty. The location is great- so peaceful! My family had funnel cakes for breakfast... I know I know, unhealthy. But hey we were in the MK and we rarely can get fried dough or funnel cakes where we live. Gotta love them! I think it would be safe to assume that it's open during the busier crowd level seasons and most probably the whole summer, considering it's in a very good location and would make money on beverages.
