Disneyland surprise

Our kids getting surprised with a trip to Disneyland. They didn't know they were already there. We've had this planned since February, calling it DL (aka Disneyland). They have been told that we are trick-or-treating in Las Vegas, and that were spending the next couple of day's in Zions (we needed an excuse for the 4 hr drive from LV to Anaheim). They really enjoyed our Vegas activities and were on board for Zions... little did they know, in the dead of night while they slept, that we were actually going to Disneyland. I even checked us into the hotel while they slept and carried them up to the room at a back door... so they wouldn't see the Mickey memorabilia all over the main lobby.
