We stayed at the Royal Plaza two weeks ago for a night. I got an amazing price directly through the DTD hotels' website---$55 per night (plus fees and tax)---about a week ahead. It was very nice and very clean, not overly large, but there was even a pullout chair for the 5th person in the room. No fridge, but we planned for that with a really good cooler to hold our food until SSR check-in the next day. The walk to Earl of Sandwich in DTD was 15 minutes from our room, 10yo in tow.
We stayed at the Doubletree the year before which was also quite nice. It was about $100 for that same night this year, so we went with a new-to-us place.
We have to look for rooms that sleep 5, so no Holiday Inn or Hilton for us.
