Pimalai on Koh Lanta is holding off on building on its spare 50 rai because Green Zone rules ban large commercial towers on the island, and the rules are expected to stay for at least 5 more years. It is growing revenue through higher room rates (about 3.5-5% average rise) and upgrades such as a 50 million baht spa renovation. Its 2026 target is 600 million baht, and occupancy was cut to about 69% after Middle East tensions slowed travel. For a small hotel or guesthouse on Lanta, the lesson is that rate and service quality matter more than adding capacity while zoning is tight.
