It looks like the Homewood Suites might work for you @ $145. It is brand-new, and while I have not stayed at this particular HS, I've stayed at plenty of others. Unless you co-sleep with your kids, HS is awesome because you have two rooms, so mom and/or dad can have some private space to stay up late, watch some TV and generally not have to creep silently around the room out of fear of waking the kids up.
Breakfast is complimentary, and is a cut above the usual hotel "continental breakfast". They usually have pancakes, and a couple of other "hot" dishes, along with the usual cereal, bagels, muffins, oatmeal, etc. They also have complimentary dinner and sometimes offer a free cocktail or two.
Finally, if you just want to crash in the room, it has a full kitchen, so you can pack food in the car and keep it in the fridge, or run to Publix and pick up a few things to get you through until embarkation.
I think Residence Inns offer a lot of the same features, but I'm a Hilton guy, so Homewood Suites is all I can speak to first-hand.
