Answer
When planning an island trip from Pattaya, such as to Koh Larn, you can buy tickets at the pier or through local travel agencies. The prices are generally reasonable and can vary based on the season. - It's good to book in advance during peak tourist seasons, especially for popular destinations, to avoid missing out. Many agencies also offer packages that include transportation and activities, which can be a great value. - Make sure to check the schedule for boat departures, as they can change based on weather conditions. Arriving early at the pier will give you a better chance of getting on the boat you want. Freshness note: Prices, opening hours, schedules, addresses and provider details can change. Confirm the current information directly before travelling or paying.
