My husband and I keep doing same things. We are looking for thing to do on date night. Any recommendation?

I assume that you are looking for activities to do in Singapore. If you're looking for something more interesting, why not go for a date at Singapore's Night Safari? Right now, Singapore's Night Safari has a promotion where tickets are being sold 50% off from 11-31 March 2016 for local residents. I'm sure you'll get to re-live those moments when you and your husband were dating. http://www.nightsafari.com.sg/events-promos/50off-mar16.html?gclid=Cj0KEQjwt763BRDZx_Xg3-Pv2cABEiQAoDfeGOUn7GvvUCBvt9C0MoN-jRmkNvtfML-qBUaV68PEQpkaAgyr8P8HAQ
