I will be arriving late at night with my granddaughter. Instead of booking another day at a hotel, is it possible to stay at an airport lounge by paying for the stay until morning? If so, how do I go about doing this?

Lounges close at night

I would if I was you stay at a hotel that us close to the airport, save you some money that way. Have a nice flight...

Will be cheaper to stay locally in a hotel

There is a nap room in the international terminal but its expensive ($80 for 2 hours). There might be some cheap hotels near the airport that may be comfortable for just one night before continuing your travels.
