From a redditor: Pickup and dropoff was no hassle to/from hotel, food and beverages provided were good. The 3 days I dove with them, the dive groups were small, maybe 4 max per DM. I was taking a course and it was just myself with the instructor. They are pricey for Thailand, but they have speedboats that go to Koh Tao or close to there everyday. I think it was around $150 USD for 2 dives + tips. https://discoverydivers.com/ Next trip, I would consider just staying on Koh Tao.
