As a PC Member they dont care. If you are trying to get in using a CC and flight coupon they may be different story and I dont have the answer to that one.

I will let you know that your baggage will most likely end up in a special lock up area. You may even want to let the service personal in the lounge know so that they can call down to baggage area and alert them. I say this because I did this same thing once at IAH an the personnel were wondering were I was. Also you take a risk of someone getting your stuff.
