Across from the main gate is the Ramada Anaheim, Best Western Plus Anaheim, Best Western Plus Park Place, Fairfield Inn... Just to name a few. There a serveral others that are also with in walking distance. La Quinta, Ho Jo, The Hotel Ménage. Good luck picking one. I have stayed at most of these and they are decent enough for the amount of time you spend in them when not in the Parks. :)
I agree with DarkwingHuck, get an AP! It will cost less than the 4 day hopper and you can play in the parks for all 5 days and get 10-20% off of most of your food and souvenir purchases. It is more cost effective.
