Aviserv is after immigration & customs just before you exit the terminal building. You can get in there with your PP but it’s limited to 3 hours. While you might be able to stretch your 3 hours a little bit... you won’t be able to stay there for 18 that’s for sure. Your PP will cover your food there. Showers, sleeping pods etc. are all extra.

Once you leave Aviserv use the elevators/stairs in the airport building (don’t go out) to go down to the prepaid taxi level (level 4 of the terminal I think). There are some cushioned chairs there you could rest on once again. I don’t think anyone will throw you out of this area.

You can easily go back from that level to level 6 which is the arrival level where there are some food stands. You can also go back to Aviserv once it’s the “next day” and you can swipe your PP in the lounge again.

You can do all this without leaving the terminal building (if you leave the building you cannot re-enter). Still, 18 hours in the airport is going to be really really tough. There will be some cheap hotels near the airport (search for Oyo hotels) or AirBnB you should try and look up.
