When are you going? We will be there the 10-15 of April, and had a kind of hard time using priceline this time because the hotels are getting busy fast! We've used priceline 8 times for Disneyland now, and my two favorites that we had gotten were the 3* Hyatt, it has a shuttle, but a $12 per day parking fee. we got it for $35 per night.
The other is the Extended Stay America, it's only a 1*, but very clean and it has a micro, full size fridge, stove top, pool, and we got it for this trip for $33
Since we didn't want to pay the parking for the Hyatt, and they don't have kitchenettes we feel we get more out of ex. stay rooms. Although the Hyatt does have 2 pools and 2 hot tubs.
however, you are never sure which hotel you will get, so it is a little hard. We have found a lot of 3* hotels charge a good sized parking fee, my theory is they are right by the convention center and a lot of business people have a business credit card to put things on that they don't pay for themselves, so they don't care about the fees, and paying a lot for the on site restaurant, but the lower stars are kitchenettes, or offer free little breakfasts since they are for the tourists more.
