Group organisers on this corridor search by headcount, not by star rating — 'villa for 15 persons', '4 BHK with extra mattresses', 'villa that sleeps 20'. It is a different search from the one OTAs are built for, which is why so many groups end up splitting across properties.
Every villa in this collection takes twelve or more people on site, with the extra-mattress capacity stated honestly rather than estimated. Use the split calculator on each listing to see the real per-head number including meals and the barbecue add-on — that is the figure your group will actually ask about.
