Having 5 day trip
 

Hi guys!!
Me and my friend have booked a holiday to kuala lumpur for 5 days! We were wondering whether it is worth doing a day trip to Singapore. We don’t know whether want travel by bus or travel by flight.
How about the price and trip duration ?
Has anyone been for a day trip and do they recommend it? The reason why I would like to do a day trip is to get a taster and if I like it to maybe book a week there next year. Thanks in advance guys
