We are going to Puerto Rico next month and I'm trying to figure out what to do about a carseat for my DD. She is 4, 41 lbs, and 43" tall. We have her harnessed in a Frontier SICT at home, but there is NO WAY I am dragging that beast through two airports. While in PR we'll mainly be using taxis and walking, though we'll probably also rent a car for a couple days. Folks here have suggested the Travel Vest, which looks great, but the price is unappealing for something we're only going to use briefly. (We are also pregnant with twins, so right now our carseat $$ priorities are about saving money to get a bunch of Radians for the back of our Accord.)
Anyway, thoughts on the Bubblebum? Is this a reasonably safe option for travel in which we won't be spending a whole lot of time in the car? I know that ideally she'd be harnessed, but I just don't see a way to make that happen. All advice or thoughts welcome.
