Going to Bangkok for tour from 5th Sep to 8th Sep. Is it safe to go or should i cancel the trip?

It's safe to visit Thailand and never been dangerous. However due to the protest all train service has stopped. Airports are open but the protest group said it may close them down again including new information this morning that they may include the Bangkok Airports. So unless something changes in the next few days, I would cancel my trip until another time.
