Hey, I have a VN flight SGN-SIN, arriving into Changi at 7:25p, and then the next morning I'm flying SQ biz class SIN-MLE, departing at 9:45am.

Rather than deal with a hotel in Singapore, or even those airport transit hotels, I'm thinking of just sleeping somewhere in a lounge. So a few questions that I'm hoping someone can answer:

1. I'm guessing that as an SQ biz flyer I'll be able to get into some SQ lounge. (There are also some Priority Pass lounges that are open 24 hours that I'll have access to: the Skyview Lounge in T1 and the Ambassador Transit Lounges in T2 and T3.) Are any of these good for sleeping?

2. Are there lockers or some other place I can ditch not only my suitcase but my carry-on backpack? I would be ok leaving my suitcase w immigration to claim the next morning, but definitely need to have the backpack (w/computer) and would need it to be secure that while I'm sleeping. Perhaps in a lounge?

Thank you very very much,
Eric
