Activity Assistant??

Back with a totally different scenario :). My facility's HR dept called me in today to ask if I would be interested to fill in an Activity Assistant position that previously went vacant. They have been interviewing for the last 2 weeks and I guess the can't quite find the right person? This position is to work on the Dementia unit (which I currently work as a cna) :) so I know each resident, their mental capacity, their likes and dislikes and besides, I actively participate in activities anyway. So HR told me this would be a 40 hour position (compared to my current 37.5 hours), I would prob get paid a little more than I am making as a cna at the moment, its a 9-5 job as compared to me being at work at 6:45am and - as he put it, the job is not as physically demanding as CNA work. I said I'll go home and think about it. I have two days to get back to them. Any pointers? Would you take this position were it offered to you? I still would love to keep my CNA license active tho. Thanks in advance.
