Thanks, John for all the good info! Yup, I think we'll just mellow out during the HKG layover. We also have Priority Pass which has what appears to be two good options in SIN in terminal 1 (our departure terminal with KLM)...the Skyview Lounge (which I believe is the Cathay Lounge) and the Rainforest Lounge.
And the Private Room for SQ departure in SIN sounds very cool!
