What's the make up of your group? If it's mom,dad,3kids and a grandparent I'd just go with a 7/8 seater minivan. If you're mom,dad,2kids a SIL/BIL and one cousin (and more than one of you can drive) I'd probably suggest 2 small cars (or one flashier one for you and give the other "family" the option of what type of car they want.
You're going to struggle to get anything that "flash" and capable of holding 6 people and their luggage JMHO.
