I live in St Cloud which is the next town East of Kissimmee. Kissimmee itself is not too far from Dowtown Disney where you will find Pleasure Island an area of bars and night clubs. It also has an Irish bar and fish and chip shop although someone needs to show them how to make real fish and chips. You cannot walk to Downtown Disney, you will need to get a cab as it is a few miles away. The town of Kissimmee has of course some bars and restaurants but it is not what you would call night life. As for St Cloud, forget it.
