If there is any opportunity of going out to Vegas I don't know how one could pass that up. I'm sure once everyone is out there you can convince your cousins to go out with you. But on the other hand, there could be times where you wouldn't mind going out solo. Remember this is Vegas we are talking about so you won't have a problem making friends while you are out there. My buddy and I just booked a trip to go out there in the third week of August. Can't friggin wait, it will be my first time to Vegas.
