Traveling in a foreign place for the first time can be nerve-wracking but it should not take away the fun of exploring a new city. When going to Bangkok, consider the weather. If you want to explore with a good weather and very minimal chance of rain then the best months to visit is from November until February. The next thing you have to do is find the best budget hotel in Sukhumvit because it is cheaper to book in advance and you will be more at ease knowing you already have a place to stay. Aside from Sukhumvit, the districts recommended for tourists are Siam and Yaowarat.
Staying in a Bangkok for a few days would be more convenient if you have your own local SIM card. At the Suvarnabhumi airport of Thailand, there are stalls where you can purchase one that comes with date and mobile packages. For those staying in Thailand for a few months, it is best to get an AIS SIM card.
Not everyone is accustomed to using technology therefore it is better to have a paper map on hand. This is usually available for free at the airport upon arrival.
The most recommended mode of transportation around the city is public transport. Tourists arriving at the airport can take the Airport Rail Links by choosing either Express Line or City Line. Transfer is then available through the MRT or the BTS skytrain. Before leaving for the airport, make sure you are familiar with the routes of these public transport systems by checking the official website.
The ticket vending machines at the stations are easy to use because of the availability of the English language and most of the staff also knows how to speak in English. Taxi is another transport option in Bangkok. The good news is that they are not only affordable but safe to use as well.
Before going to Bangkok, make sure you have enough local currency to use on public transport. Credit cards can be used in best budget hotel in Sukhumvit but if you need additional cash, it is better to change money at a local company rather than inside the airport.
