Start with location: Koh Samed, Hua Hin, Chanthaburi, Chumphon, Phang Nga, or Rayong. Then pick vibe: beachfront relaxation with family amenities (Anantara Hua Hin, Best Western Plus Carapace Hua Hin), wellness retreats (Thailife Meditation & Wellness Resort, Saikaew Beach Resort Koh Samed), or luxury golf-and-beach (The Nouveau Chumphon Beach Resort & Golf). This helps shortlist hotels that match your priorities for a long stay in Thailand.
