Perhaps "Dick's house" is code for Universal's Wizarding World of Harry Potter.
As others said, I think the problem was that they told the kids that they were going one place and then changed gears. Many kids don't like change. If they were just sitting around the house watching television and were surprised with the trip, I think it would have been a different scenario.
I can't surprise my kids with something like this for one reason --- I can't keep a secret. From the moment I decide we are going on a trip, it is all I talk about during dinner and car rides.
