❌ Koh Samui Disadvantages:

- Beach quality 8/10 vs Phuket 9/10: Beaches excellent but not QUITE as stunning as Phuket's best (Kata, Railay access)
- Flights pricier: Bangkok-Koh Samui $100-180 vs Bangkok-Phuket $80-120. Airport monopoly = higher prices.
- Fewer activities: Overall less to DO beyond beaches compared to Phuket's variety
"Koh Samui perfect for our family's needs. Having airport on island was GAME-CHANGER — no ferry nightmare with 2 kids under 8. Chaweng Beach calm water, shallow for ages. Kids built sandcastles for hours. Fisherman's Village Friday market fun. Felt more relaxed than friends' Phuket trip. Less to do but we wanted beach relaxation anyway."

Frequently Asked Questions
Is Phuket or Koh Samui better for families?
Phuket better for first-timers and active families — better beach quality (9/10 vs 8/10), day trip access to Phi Phi/Railay (iconic Thailand), more activities/variety. Koh Samui better for young kids (under 8) and relaxation-focused families — airport ON island eliminates ferry stress, calmer water, more laid-back vibe. Cost similar ($3,500-5,500 for 7 days). Choose Phuket for adventure/best beaches, Koh Samui for ease/simplicity. Both excellent choices.
Which has better beaches - Phuket or Koh Samui?
Phuket wins beach quality 9/10 vs Koh Samui 8/10. Phuket's Kata, Karon, Nai Harn + day trip access to Railay (10/10) and Phi Phi (9/10) = better overall beach experience. Koh Samui's Chaweng and Lamai are excellent (8/10) but not QUITE as stunning as Phuket's best. HOWEVER, Koh Samui's Gulf water generally calmer/clearer than Phuket's Andaman Sea — better for very young kids (ages 3-6). For families prioritizing BEST beaches, choose Phuket.
Is Koh Samui easier to get to than Phuket?
YES — Koh Samui MUCH easier with kids. Airport ON island vs Phuket requires flight + 45-min taxi. Koh Samui: Bangkok flight 1 hour → land on island → taxi 15-30 min to hotel. Phuket: Bangkok flight 1.5 hours → land airport → 45-min taxi through traffic to beach areas. For families with young kids (under 8) or lots of luggage, Koh Samui's convenience is HUGE advantage. No ferry stress, simpler arrival, less travel exhaustion.
How much does Phuket vs Koh Samui cost?
Nearly identical — both $3,500-5,500 (family of 4, 7 days island stay). Koh Samui flights $80-240 MORE than Phuket (airport monopoly pricing), but accommodation, food, activities similar cost. Don't choose based on price difference — choose based on priorities. Phuket slightly cheaper overall due to flight pricing, but difference $100-200 total trip (negligible). Budget travelers can do either $3,000-3,500 with guesthouses and street food.
Can you visit both Phuket and Koh Samui in one trip?
YES — many families do both! Ferry 5 hours $40-60/person OR fly 1 hour $80-150/person. Common itinerary: 5-7 days Phuket (Phi Phi trips, Railay, activities) then 3-5 days Koh Samui (relaxation, different vibe). Gives best of both worlds. Minimum 10 days total needed (shorter feels rushed). 12-14 days ideal for leisurely split. Ferry overnight option exists (saves hotel night, kids sleep through). Flight easier with young kids (luggage, tired children). Worth doing both if 12+ days available.
Final Recommendation: Both Phuket and Koh Samui deliver exceptional Thailand family experiences. Phuket wins beach quality (9/10) and activity variety (Phi Phi day trips game-changer). Koh Samui wins ease (airport on island huge advantage young kids) and relaxed vibe. Cost nearly identical ($3,500-5,500). Choose Phuket for adventure/best beaches, Koh Samui for simplicity/relaxation. Can't go wrong either choice!
