I'm planning to take a quick trip to India next month, basically just a weekend jaunt in Agra and Delhi...my TG flight from BKK arrives at about 22:45 and I intend to go to Agra early in the morning (6:00 AM express train).

Now, what with transportation, going through immigration and customs & such, I reckon there's only about 5 hours left for "sleep"...I generally like to stay in nice hotels, but for just a few hours that night Delhi is quite pricy and imho not really worth it.

I definitely don't want to stay in some dump, I'd much rather spend the time having a few drinks and watching something on my laptop in, let's say, a restaurant in the terminal...is there any decent place where I can do that? Can I buy some kind of lounge pass (if one is open at night)?

How about hanging out in the city during that time? Safe, worthwhile...?

Thanks in advance for any advice
