Would I be able to get to the lounge when I arrive, or would I find myself forced through immigration because my flight is the following day. Thanks!
Rules for the sleeping rooms are very restricted. Don't think your itin qualifies, but then I don't remember exactly what the rule sheet said.
You will make it to the lounge without immigration.
There is also a decent transit hotel inside the terminal (no immigration either).
