I'm less anti-lounge overnighters than people who try to use the lounge and then enter HK.

I've also done overnight connections and do appreciate the other point of view - if I have an overnight connection with a crack-of-dawn departure the next day, I want to stay somewhere at or near the airport, minimise my risk of missing the flight and not have to hassle walking long distances/finding shuttle buses timetables (some chain hotels are awful publishing shuttle bus timetables)/workaround when those damned shuttle bus timetables don't work.

I've done one sleepover at Changi after SIN DO SIN DO 2023: 13 - 15 January 2023: USA Martin Luther King Jr Day Weekend ; but I did want to visit the QR Premium lounge the night before, the cost was I really have few alternatives but to sleep for a few hours in SATS lounge after that.

And I've done a fair few overnight connections in the last year on RTWs:
- HND, KIX: First Cabin. No brainer. These things are built for overnight connections - if you don't use them then you're a certified miser.
- NRT: 9 hours capsule. Not as enjoyable
- LAX, ORD: standard airport hotels. I walked to the Courtyard LAX from the terminal, couldn't figure out the shuttle. I figured out the shuttle for the Hilton Rosemont.
- SYD (I wanted to be back in SYD for QF Flounge, my brother's on the other side of town): I took up Noel Philip's suggestion of staying in the Mantra. Quite long walks.

(Other than the Japan examples) These do take more effort to plan, monetary outlay, working out bus timetable and/or long walks to/from the property. I do see the attraction of some people who [mod edit] will just sleep in the lounge/in a chair/on the floor.
