Hi, what is the best, closest place to buy inexpensive booster seats once you're already at WDW? We'll be picking up a rental on site at either the Dolphin or car care center. Any big box stores close by?
There's a target too. I've done this in the past also and went to Walmart and purchased a car seat for one of the grand kids prior to their arrival. We found it chaper to buy a new seat than to rent one at $9 a day (plus tax) and we took it home with us.
Have you thought of flying with your own boosters? We simply check them in with our suitcases. Southwest puts them in a thick plastic bag and labels them for us. We've never been charged anything and they have always arrived undamaged with quite a few others I might add!
