Have you checked Park Vue Inn? I recently read a comparison of the 2 properties on this forum and PVI came out way ahead. Free wifi, parking, breakfast, and even closer to the parks. There have been some unhappy customers who have had issues with their customer service when things didn't go right, but the same can be said of most properties, including Carousel. Still, I've always been a little afraid to try it since one of the complaints involved bed bugs and there was nothing done for the customers. Any hotel can run into a bed bug issue but if they refuse to deal with it, that's another issue.
I stayed at Carousel last month and have a reservation for next week. We found the staff to be very nice, the room pretty, the distance great but the parking is ridiculous and to charge $14 plus a 'resort fee' which gives you NOTHING is annoying. However, we got a very good rate ($89) so those things were minor to us. If I were spending $150+, I'd look elsewhere.
The thread I mention had a link to someone who was blogging about the 2 hotels, and they'd used an app called Hotel Tonight to get the $89 rate as well. Downside to it is that you can't book very far out, so if it's a busy time and you don't want to risk it, that won't work for you.
One other possibility you might try is Anaheim Plaza Hotel. They are an older property, about the same distance from the parks as Hojo but in the other direction. They used to be cheaper than most of the others, but I haven't checked them in a long time. The rooms are very large, you get a mw, there's a giant pool and most rooms have a large balcony or terrace. Kind of funky kitschy...old school type place. And Hojo is great for families, but I think their prices have gone up substantially.
