Are you talking about the Anaheim Hilton by the Convention Center?
If so their rooms are OK. I have stayed there several time over the past three years (for conventions) The rooms only have double beds not queens so if that is important to you ..... I prefer both the DLH and the DGC over the Hilton. Many reasons but the Hilton is not Disney, their rooms are overpriced, longer distance to Disney (they used to give free ART passes but don't now). On the plus side they do have rooms with a Disney view so you can watch the fireworks if lucky enought to get one of these.
