Plan Thailand without doing 7 islands in 10 days
Thailand is bigger than it looks on the map. Bangkok to Chiang Mai is 430 miles. Bangkok to Phuket is 540 miles. A "2-week Thailand trip" that includes Bangkok, Chiang Mai, Phuket, Krabi, Koh Samui, and Koh Tao means 5 flights or long ferries and you'll spend 4 full days in transit. The planner here enforces 2–3 regions max: typically Bangkok + one northern city (Chiang Mai) + one beach (Phuket or Krabi).
The 10-day Thailand classic
Bangkok 3 / Chiang Mai 3 / Krabi or Phuket 4. Day 1–3 Bangkok: arrive, jet-lag day at hotel pool, Day 2 Grand Palace + Wat Pho + riverside sunset, Day 3 Chatuchak Market + dinner in Ari or Thonglor neighborhoods. Day 4 fly Bangkok–Chiang Mai 1h15m ($45–$85 Thai Smile or AirAsia, book 60 days ahead). Day 4–6 Chiang Mai: old city temples + cooking class ($35/pp, Thai Farm Cooking School) + Elephant Nature Park ($90/pp for ethical sanctuary — NOT elephant riding which is now cruelty-condemned). Day 7 fly Chiang Mai–Krabi 2h with layover in Bangkok $110–$180/pp. Day 7–10 Krabi: Railay Beach, Four Islands tour ($22/pp), ferry to Phi Phi ($28/pp round-trip for a day). Day 10 fly Krabi–Bangkok–home. Total for two: $2,800–$4,200 all in from U.S. West Coast.
The 14-day Thailand deeper trip
Bangkok 3 / Chiang Mai 3 / Chiang Rai day trip + Pai 2 / Phuket 3 / Similan Islands day / Bangkok 1. Add Pai (3-hour minibus from Chiang Mai, $12/pp, mountain hippie town — nightly food market, Pai Canyon sunset). Add Similan Islands snorkeling day trip from Phuket ($90/pp, best reef diving in Thailand, November–April only, closed May–October). Total for two 14 days: $3,800–$5,500.
Bangkok: 3 days done right
Stay in Sukhumvit (Soi 11 for nightlife, Thonglor for food, Asok for metro convenience) or Silom for riverside. Hotels: Arnoma Grand $75/night, Volve Hotel $95/night, Pullman Bangkok Grande Sukhumvit $160/night, Mandarin Oriental $720/night. Day 1 arrive and eat — Soi 38 street food, Raan Jay Fai (Michelin-starred street food, $50/pp, 4-hour wait — go for opening 2pm). Day 2 Grand Palace ($17, dress code: covered shoulders and knees, closed afternoons) + Wat Pho reclining Buddha next door ($7) + Wat Arun ($3) across the river by $2 ferry + river sunset dinner at Supanniga Eating Room ($40/pp). Day 3 Chatuchak Market (Saturday/Sunday only, 15,000 stalls) or Lumpini Park morning run + Jim Thompson House ($7) + dinner in Thonglor at 80/20 or Gaggan Anand's places.
Chiang Mai: what to do
Old City is 1 km × 1 km square surrounded by 700-year-old city walls and a moat. Stay inside Old City at 137 Pillars House ($180/night, boutique) or outside in Nimman neighborhood for modern cafes at U Nimman ($75/night). Must-dos: Wat Phra Singh + Wat Chedi Luang ($2 each), Sunday Walking Market (3–10pm on Ratchadamnoen Road), Thai cooking class (full day $35, Thai Farm Cooking School, includes market tour), Doi Suthep temple ($3, taxi $10 up the mountain), ethical elephant sanctuary (Elephant Nature Park or Boon Lott's — $90/pp full day, do NOT ride elephants or visit tiger temples). Food: Khao Soi Khun Yai (coconut curry noodle soup, $3), Dash! Teak House for Thai fine dining ($28/pp), Cherng Doi Roast Chicken ($7/pp).
Beach strategy: Phuket vs Krabi vs Koh Samui
Phuket: most developed, biggest party scene, most restaurant variety, easiest direct international flights. Stay in Kata (mellow beach, good food) or Patong (party — avoid if you're over 35 unless you love EDM). Krabi (actually Ao Nang/Railay): dramatic limestone cliffs, boat culture, quieter, more natural beauty. Stay in Ao Nang. Koh Samui: middle ground, family-friendly, good for 5+ day stays. Requires flight to USM airport. Koh Lanta: quietest of the four, best for couples seeking chill. Phi Phi: overrun day-trip destination, don't stay there.
When to go
Peak (November–February): dry, 85°F, 40–60% hotel premium. Book beach hotels 4 months out. Shoulder (March–April): hot (95°F), dry, smoky in the north due to rice-burning season — Chiang Mai air quality is bad March 15–April 30, visit then only if you're not sensitive. Monsoon (May–October): cheaper 40%, frequent 2-hour afternoon rainstorms, beach conditions vary, Similan Islands closed. Best month for weather + price: November after monsoon ends. Best for budget: September for shoulder pricing with acceptable weather.
Thailand food safety
Eat street food at busy stalls with high turnover — the food is safer than in tourist restaurants because it's cooked fresh and eaten immediately. Bottled water always, even for brushing teeth in cheaper hotels. Ice at restaurants is commercially made and safe. Don't eat cut fruit from street carts (washed with tap water). Avoid raw shellfish (som tam with raw crab, oysters). Otherwise eat with abandon — Thailand has a legitimate street food Michelin recognition system.
Money and logistics
Cash: 30,000 baht ($830) for 2 weeks mid-range. Use Bangkok Bank, Kasikorn, or SCB ATMs with your Schwab debit card (no fees) or Fidelity Cash Management. Credit cards accepted at hotels, major restaurants, 7-Elevens, but not most street food. SIM: Airalo eSIM 10 GB/30 days $22. Visa-free entry for Americans up to 30 days. Grab app for taxis (not street taxis — overcharging is constant).
FAQ on Thailand trips

Hep A/B if you don't have them. Typhoid if going rural. No yellow fever unless coming from an endemic country. Diving trip? Koh Tao has the cheapest PADI certifications ($280 for Open Water). Similan Islands is the best Thai diving (liveaboard $750–$1,400 for 3–4 day trip). Can I extend 30 days? Land arrivals get 30 days, flight arrivals get 30 days, extension at immigration office +30 days for 1,900 baht ($52). Taxis vs Grab? Always Grab or Bolt. Street taxis overcharge or refuse meter. Tipping in Thailand? 10% at nice restaurants (not always included), round up at casual places, 20 baht ($0.55) for bellhops, no tip for street food.
