Given these options and your party mix of 4 adults and 1 child, my choice would be the cheapest you could do with 2 rooms.
You're going to spend most of your waking hours together. Get two rooms so you have some alone-time at night, and 2 showers in the morning.
Then it becomes a matter of how much you want Club level. We've done the Hard Rock Club level twice in the last 7 months. It's good but the only way you're going to get full value out of it is to be at the 5-7 PM happy hour and drink!

(And that's a lot of drinking over a long trip.)
We found the Hard Rock's Club level gets somewhat tedious by the third night.
