One of my flight options are a 24 hr layover in HK. I am an Indian citizen. I am thinking of buying that ticket and venturing out into HKG city. I looked up the trasit visa option for which I can be pre-approved before arriving - it is valid for 48 hours. I can also keep my hand luggage in storage for $140 HK$. I can take a train from the airport which would drop me off in the heart of the city. Am I covering all my bases. Have any of you done this before. Any tips?
