Villas and suites. The index measures the 5★ hotel median in every area — $213 a night island-wide in Oktober 2026, n = 95, with Surin the dearest area at $413 — and the monthly median of 4-bedroom-plus villas ($7,845 a month, n = 35). Above the index sits the staffed-villa market, priced per night by the agencies that manage the houses: $840–3,600 for a 5-bedroom villa at Cape Yamu, $1,280–6,500 for 5–6 bedrooms on the Kamala headland, $1,500–7,650 for a 6–7-bedroom estate. The luxury-villas page puts these next to the index by area.
Yachts. A crewed sailing catamaran for up to eight is €800–1,000 (≈ $900–1,125) for a day with lunch on board; a 60 ft motor yacht for up to fourteen is 170,000 THB (≈ $5,088) in the low season and 200,000–230,000 THB (≈ $5,985–6,883) from November to April; a week on a crewed superyacht starts around $60,000 before the provisioning allowance of 25–35 % and 7 % VAT. The yachts page has the routes — Phang Nga Bay, Racha and Coral, Phi Phi, the Similans — with the marinas they leave from and the months the sea is calm.
Helicopters. One licensed operator, Skydance Helicopters (Advance Aviation), flies from a heliport beside the airport: a 30-minute scenic seat is 10,900–11,900 THB (≈ $326–356), the whole aircraft for about forty minutes is 51,900 THB (≈ $1,553), and the two-hour circuit over Phang Nga, Krabi and Phi Phi is 144,900 THB (≈ $4,336). Transfers from the airport to a villa or a resort helipad are quoted per flight on request; the helicopters page has the seasons, the rules and the weather months.
Private tours. The eight day trips the index prices as join-in seats exist as private versions: a private speedboat to Phi Phi at 47,900 THB (≈ $1,433) per boat, a luxury longtail for a beach day, a private guide for the Old Town, a car and driver for the sanctuary and the Big Buddha. The private-tours page shows, for each trip, the group size at which the private boat costs the same per head as the join-in median.
Chef, spa and events. A private-chef dinner in a villa runs 3,500–12,000 THB (≈ $105–359) per person for a group of four to six; a full-stay chef is usually quoted at 15–30 % of the villa rate. A 90-minute treatment at a resort spa on the Laguna estate is 5,400–6,000 THB (≈ $162–180). A private evening — a villa event fee of 25,000–100,000 THB (≈ $748–2,993) plus a DJ at 40,000 THB (≈ $1,197) — is the scale of a celebration for twenty; a full villa wedding with production starts around 1.5 million THB before catering, and is a different conversation.
