Will be flying into MCO late January and I can have a choice of a PCAR (Hyundai Genesis) , LCAR (MB C series) or a XCAR (MB E series) for a very very good price. I'll be hauling my 2.5 yr old toddler Oscar with me so which car should I rent for the week? We'll be heading to Clearwater Beach where I have a conference. Which car would have the biggest sunroof for my Oscar to look out at?
