thanks guys for some inputs...more thanks to the longer input.

i also had bad experience via bahrain (some how had to stay in hotel 2 times for long transit hours). hotel and food were good but that comes only after a lot of trouble u have to go thru...so i don't recommend that at all.  airport was similar to railway stations.. ppl shouting, many officials and passengers angry for various reasons, restroom unusable, long long waiting time for transit passengers etc etc..

so wanted to make sure delhi wasnt like that... or even if it was would be prepared for that...
