Recently we've been staying at the Tropicana. It's very specific to our situation where we like having a multi room suite since we have young kids. We stay at the Park View Suite right at the front of property, usually on the 3rd floor. There's an elevator with no wait, a king bed, a pull out couch, and a pull out chair. We have two bathrooms and separate space when the kids go to bed. It literally takes 5 minutes from room to security. We have easy access to tons of affordable offsite food options. We also have a balcony overlooking the monorail and the fireworks!
Yes, it is not a perfect hotel and there are pros and cons. It's been working well for us and next year will be our 4th time!
We've also stayed at both Best Westerns on Harbor. We have done Sheraton. The Fairfield and Courtyard also look like good options, but we haven't stayed there. I have a friend who likes Anaheim Hotel.
At this point in our lives we value: 1) close proximity, 2) clean rooms and bathrooms, and 3) multiple rooms.
