I think you might be right. Chris Pratt is a DVC member. Checking in a week later than me might be because they are sailing a week later.
Does your cruise go to Castaway Cay as well? I noticed they said double dip Lighthouse Point but didn't mention Castaway at all.
Tim brought Da Baby to the park Monday morning. Wednesday they all went to the library together. It seemed like, at least in this home vlog, Rosie wasn't around (or mentioned). The cruise is still 30 days away, so I wouldn't think she was making up for time already. The last time that she was mentioned was the home vlog before the Hot Wheels thing where Jenn said that Rosie had to make up a day because she was "sick" and she would be working on Saturday that week and that Jenn can go to the Hot Wheels thing with Tim and J$. Jenn did not go. She didn't even appear in the home vlog section of that video and it was never mentioned why she didn't go.
Nanny always seem to quit on them after a cruise, so I can completely see Rosie getting home from that Spring Break cruise and looking for another job. Jenn had mentioned she was "sick" at least 3 times since they've returned. I don't know about everyone else but when I was looking for a new job, I always called in sick to my current job.
