After a 30-minute tour of Cham Island with the guide, and a bit of snorkeling, we moved to the lunch spot, ate, and relaxed on the island until around 2 PM. Lunch was just okay. You need to order a drink if you want to relax on a sunbed. I heard that Korean tour companies have parties, but I prefer quiet, so just relaxing wasn't bad. The party-loving crowd might prefer the Korean tour companies.
