Hilton Jumeirah is nice, I stayed there few times, although I prefer Le Royal Meridien which is few hundreds meters away. Obviously the newest and freshest HH addition is Conrad Dubai. It is a very nice hotel with probably the best relaxing and pool area out of all hotels in Sheikh Zayed Road but... yes, it is located in SZR which means you need to take a cab if you want to get to the beach / the walk.
