Might try looking for an Embassy Suites. Get two separate rooms. The bedroom will have two double beds and the living room will have a pull out sofa. If the kids crash early you and the missus can still stay up a bit in the other room. There is snacks and drinks in the evenings and a full breakfast in the AM.
There is an Embassy Suites listed as a TPA hotel. See what the rates are. I think there is a Waffle House or Denny's walking distance (but am not sure). If there is they are both open 24/7 and would do ok for food in the morning.
