India - Hyderabad - layover for 5 hours, arriving at 1230am, next flight 530am

Hi - I'm flying in from Singapore arriving into Hyderabad HYD (SIN-HYD) at 1230am. my next flight is at 530am via JetAirways to Pune PNQ (HYD-PNQ). Since my port of entry will be Hyderabad, wondering the following:

1. Will there be JetAirways rep available to issue me a boarding pass so that I can get back to airport security for lounge at 1230am
2. Should I stay at hotel for the 5 hour layover
3. What are the best options

I cannot rebook my flight... somehow... very long story my booking evolved into this...

Thank you!

which airline will you be flying from sin-hyd????
