The Anabella looks like a nice hotel. I have never stayed there, but I have stayed at a nearby hotel, the Jolly Roger. It will be a bit of a walk to the DL front gates. Otherwise, you can buy a bus pass. The hotel may have their own transportation to DL. Or you may have your own rental car? There are other nice hotels directly across from the gates. Here's a good map showing proximity.
Bret's Disneyland Lodging LinkMap Our favorite hotel is the Candy Cane Inn. We have stayed at 6 good neighbor hotels and this is the best one by far, IMO. If you have any more specific questions, post them here. Have a great vacation.
