Im not a 100% sure on the quayside although im pretty sure it is around 150SGD with about a 20/30 dollar difference for depature service.

Agreed, I thought it was a good deal although there suites run quite high, although I guess if you only spend one night in one you get some bang for your buck

Yep, like I said before it was a pretty frivolous expense, but a great thing to experience once. The quayside service is much more reasonable with all of the same benefits minus the drive to the terminal.
