From website:
To celebrate the re-launch of Singapore Airlines Holidays, we have a limited number of short breaks to Singapore from only $995 per person.
We have 50 holidays available at the promotion price of $995 per person. Prices are based on two people sharing a standard room staying at the Peninsula Excelsior Hotel. Valid for departures 25 April to 26 June 2014 or 25 July to 18 September 2014.
For other options, please see the prices tab.
It's hard to judge the value of these holiday packages. So for 2 people, since it is twin share, will be $1990. Two people could fly on Scoot (eg. Gold Coast - Sing, depart 14 May) for $928 return (including baggage and meals) and then stay 3 nights for $600 at the Pen Ex Sing, returning on the 17 May. Total $1528.
