Leavin' On A Jet Plane

We're headed out to Florida tomorrow. My Pop and his wife are in Tampa (more specifically, Valrico), while Hubs' folks are in Sarasota (more specifically, Siesta Key). I can't wait to have uncles and aunties and grandparents available to hold Huxley, listen to him giggle, and dip my feet (and his!) into the ocean.Before I go, I thought I'd solicit travel advice from all you parents out there.
