Not me. My go to is Grand Legacy at the Park, but I have also stayed at Desert Inn, the Fairfield Inn, the Anaheim Hotel, and the Castle Inn once many years ago. The Maingate is too far in my opinion, and is rated #124 out of 128 Anaheim hotels on Trip Advisor. I would avoid just because of that, and this shows me all I need to know.
There are many better options.
