I can't determine if they did or did not stay the night, but It looks like the room they toured in the first video was not actually the room they stayed in. The room they toured had a door to a connecting room and the one they showed all messy did not have a door. It does look like Marriott hosted several people, so I assume they just had everyone use the same room to film in. That would explain why all their crap wasn't in the room when they toured it.
But, there definitely were some abnormal things in these vids that were not very Tracker-like, as others have mentioned. They didn't even show their breakfast meals. I almost think they didn't even eat there, but there was that shot of Jackson with the flamingo, so maybe? There were tons of voice overs. I suppose the background noise could have been too loud so they had to voice over? Or maybe Jess was too loud again. But then, at the pool the audio was awful, like they were all talking underwater. I would think that was a good place to voice over. Tim seemed to go back and forth between shirts, so that made it hard to figure out the timeline too.
And Tim sure did a lot of things without the family including the water slides and that firework gathering. All in all it was an odd couple of videos. I sure hope the Marriott rethinks their "media" invites next time.
