I have a flight from Dubai to use in February . I am flying first class. My flight leaves around 9am, but I was thinking of checking in to my flight the night before around 11pm, and enjoying the first class lounge for a long time.

Will this work? Will there be a check in Desk open at 11pm? Will lounge let me in the early before flight?

Also could the chauffeur pick me up from my hotel that early before a flight?

Thanks!
