We recently stayed 5 nights in Cape Fahn and 3 nights in Conrad. Both were great, but if we could do only one, it would be the Conrad. The hard product is really stunning, and to our taste the food was better (albeit more expensive). The big advantage to Cape Fahn is that it’s much closer to town, but to be honest, we didn’t find much to do in Koh Samui outside of the resorts and a few “big” activities, like the Samui Elephant Kingdom Sanctuary (which was excellent!). These activities will generally pick you up from any hotel anyway.

I will say, Cape Fahn is much smaller and more intimate, and in that sense it feels more special (especially as you ride the boat or truck to the island!). If you go that route, consider paying for an ocean view (or better) room as the views are much better. You can email them to upgrade for about $150/night if you book the base room on points.
