Singapore Airlines - Downtown Check-In

I'm just wondering whether anyone on here knows about or has experience of the downtoan check in with Singapore airlines, on Orchard Road in Singapore.
Basically we're flying on the A380 and would really like to bag some of the 'pair' window seats upstairs, and seen as OLCI isn't available to us due to our tickets, we're thinking using the downtown check-in 48 hours before is our best option.
The SQ website says that we will 'have to present baggage for acceptance' - does this mean that we would have to do without our suitcases once checked in?! [?]Don't think we'll bother until the day of the flight if this is the case!
