The essence of what you get with predictive search is:
As you type, Google's algorithm predicts and displays search queries based on other users' search activities and the contents of web pages indexed by Google. If you're signed in to your Google Account and have Web History enabled, you might also see search queries from relevant searches that you've done in the past. In addition, Google+ profiles can sometimes appear in autocomplete when you search for a person's name. Apart from the Google+ profiles that may appear, all of the predicted queries that are shown in the drop-down list have been typed previously by Google users or appear on the web. (from the horse's mouth)
It goes on to say In some cases, there may be a search term that seems surprising to you, but after doing some searching on the web, you may discover that it's a popular phrase online for some reason that you didn't anticipate. Queries in autocomplete are algorithmically determined based on a number of factors (including search term popularity) without manual intervention.
What happens if you actually search for "[the hotel name] for sale"? You might find that there was another hotel with the same name that was for sale!
