Money: Carry small cash bills - many places don't accept cards or give change for large notes
Weather: Monsoon season May-October - bring quick-dry clothes and waterproof bag

Visa & Travel Tips

Check visa requirements for your nationality - many get 30-day visa-free entry to Thailand
Buy a regional SIM card (TrueMove or AIS in Thailand) ~$10 for 30 days with data
Get travel insurance that covers multiple countries
Start in Bangkok and travel clockwise or counter-clockwise - this itinerary minimizes backtracking
Book overnight buses directly through your hostel - they get better prices than online
Drink bottled water only - avoid ice from street vendors if you have sensitive stomach

Rent a Car & Drive Free

Budget travel emphasizes affordable transportation—self-driving contradicts budget goals. Car costs ($40-80/day) + fuel (€0.40-0.80/km) + parking (€5-25/day) + insurance (€15-30/day) = €100-150/day overhead. Instead use: buses (€10-40/trip), trains (€20-80), local transit passes (€10-30/day), ride-shares. Backpackers maximize value via overnight buses/trains (save hotel). If destination requires self-driving: split rental among group, use budget rental companies, book longer periods for discounts, leverage free parking/camping. Calculate total self-drive cost vs. public transit to verify savings. Many budget destinations have excellent, cheap bus networks—use them instead. Sleeping on transit saves accommodation costs.
