Yes it will be lighted as it should open till at least 9pm.But do not expect the lightings to really showcase the your shots.Plants/flowers shots are ideally for day shootings,if going by the norm.
And, for added info,the new Sentosa Boardwalk,the link from Vivocity to Sentosa just alongside the existing bridge,will be open this Saturday, 29th Jan.
Should be very nice for night scenes photography.Dont miss.
Public should be able to stroll through daily till night for free without actually entering Sentosa if you dont want to pay the entrance fee.
And there will be flowers, plants as well lining this new Boardwalk in conjunction with Sentosa Flowers 2011.
