Bus to Melaque

Hola! Has anyone taken the coach bus to Melaque, Jalisco recently? We are planning to visit there. How long should the bus trip take and what should we expect along the way? Our customer service person could not speak English and we can not speak/ understand much Spanish. Any advice would be welcome.
Gracias,
Sandra y Trevor
