The self-parking garage is across Pacific Avenue from the hotel. There is a sky bridge on the second level. As you enter the main building from the sky bridge you will observe an escalator which goes down to the main level. There is an elevator next to the escalator. Take the elevator down to the first level and the check-in desk will be straight ahead of you. The hotel elevators are directly opposite the check-in desk.
The coffee shop, buffet and other restaurants are on the second level. They are accessible from the hotel elevators. The elevator near the sky bridge does not provide access to the restaurants
Here are pictures of an accessible room at the Hilton.
We stayed in room 932 in May 2012, after the transtion from the Atlantic City Hilton to The Atlantic Club Casino. The room has two double beds, a roll-in shower, a refrigerator, coffee makermaker and a safe. It has a nice view of the ocean and Boardwalk.
