Quick question: I'll be arriving in DEL T3 on a domestic AI at 2230hrs and have a connecting SQ flight next morning also T3 at 0730hrs.

I'm just looking for a place (preferably a closed room rather than open area) to sleep and maybe shower without leaving the airport. What would you guys recommend?

I'm not sure if there are any issues posed by not having my SQ boarding pass by the time I arrive on AI, but I can try to print it out the day before doing online checkin.

I've seen Sams Snooze and Eaton Smart from preliminary research. How are they? Thanks.
