Planning to stay at Four Seasons Mumbai for 1 night as a stopover.

However, I am arriving in Mumbai at around 4am. My onwards flight the next day is at 8am, so I will need to leave for the airport at roughly 4am.

I plan to use the hotel pick up BMW to take me to the hotel when I arrive, but seeing as my room won't be available for quite a long time, I am wondering if I would be eligible to use the AER Bar free of charge while I wait?

Of course, additionally, I will also take the hotel limo tour to a few places of interest around the city, because I want to get back to my room as early as possible to make the most of the small amount of time I have in this luxury hotel.
