Our recommendation is to stay in the city centre where you will be able to enjoy the sights and sounds and nightlife of Bangkok, instead of staying near the Event Venue.
Bangkok BTS Sky train is probably the easiest way to get around Bangkok, avoiding the notorious traffic jams. It may not be as comfortable as flagging a taxi but you definitely will get to your destination on time without having to be stuck in a jam for an hour or more.
There are 3 rail lines in Bangkok, namely – BTS, MRT and Airport Rail Link. All rail lines are well connected at various interchange. However, their fare system are not similar and their fare cards are different too. So you can’t use the BTS (Rabbit Card) on the MRT.
The most convenient alternative to reach BITEC is via the BTS Sky train. If you are travelling with the BTS Sky train, you should alight at "Bang Na Station" - Exit 1. From there, you will need to take a short walk to the skywalk leading directly to the Welcome Hall.
