I have a question! If u have traveled somewhere caribbean, did u bring a carseat? I know in Aruba that mostly the city bus is the way people travel, or walk. I figured our umbrella stroller would be fine bc DS isnt overly thrilled about being in a stroller anymore anyways. I know he wont sit in the carseat on the plane, so can i forgo it? We arent renting a car or anything...just curious thanks!
