I say look into booking flights. You are there in a short time, which means more time with the baby, less aggravation of traveling, no passport required, no worries about meals or about the RV breaking on the road...I can go on. You may find it a lot cheaper flying and relaxed when you get there. You can come back earlier or later if you so wish and don't have an RV to clean up when you get back. Save your money and rent a car there...My two cents.
