Ann - a note, a convertible has little to no trunk space, maybe enough for one suitecase, or two smaller ones. You'll have to load them into the back seat, and you'll have limited room because of your son. We found this out the hardway during a Hawaii trip. We had 4 bags, but luckily it was just DH and I and we piled those that didn't fit in the back seat, and it was FILLED.
