Hi Attithi, the taxi ride from Hilton Al Jadaf to The Atlantis at the Palm is approx. a 30-40 min ride and it will cost you around 45-55 Dirhams (~15 USD)

Post covid no more restrictions at all. Several app that one can use to get food delivered ie Careem.

I had almost the same flight and upon our arrival with the Hilton Hospitality we were offered a room with a minimum price for early check in which we appreciated as we knew that check in is at 3pm. There is always a solution however you can ring the hotel prior to your departure to make them aware of your expected time of arrival in Dubai as it is 10-15 minutes away.
