Practical Tips for Luxury Spa Bookings
Luxury hotel spas generally require reservations at least 24 to 48 hours in advance, especially for afternoon and weekend slots. Arrive 30 to 45 minutes prior to your scheduled treatment to fully enjoy the steam rooms, vitality pools, and herbal teas. A service charge (10%) and VAT (7%) are automatically added to hotel spa invoices, though handing 200–500 THB directly to your individual therapist is customary for exceptional care.
