I found $297pp on Southwest and I'm happy to get it - prices on other airlines have been sitting right around the $360pp mark for bad flight times with ugly layovers.

I have to wait to book though - we're traveling with my mom, sister, and nephew, and they cannot make up their minds if they want to go in a day early and visit the Kennedy Space Center. I asked them to PLEASE make up their minds by today so we could book right away... but no.
So, I'll be doing the "yay we booked our flights" dance HOPEFULLY sometime this weekend!
We did decide to fly home late on the 4th, getting a day room at the Hyatt MCO so we can swim and relax before our flight. I balked at the price of the Hyatt initially, but now that Southwest rates are out I see that the latest flight Saturday is the cheapest, so we *almost* make up the cost of the Hyatt room by taking that final flight.

And I'm still hoping to get the Hyatt on Hotwire as our trip approaches.
