Wow, that is a tough call. Is the $25 day for the roll away for both rooms? Because the Deluxe has a sofa that the 6yo can sleep on. You could bring a pool float to use as an air mattress for the 6yo. Takes up less space than the aero and could fit in the smaller room and save the $25. So the question comes down to, can each person get $5+ a day in value from the club level. I think yes and I would probably go with the club level in your case.
