I have been traveling fairly consistently to Vegas now for about 5 years, mostly staying at Bally's or Planet Hollywood (depending on which one will comp me). When my wife travels with me I use her as my companion and end up at PH. I have never had them ask for her, her card, or id when we check in. Half the time she is in the casino by the time I get to the front of the line anyway. My question is this: If she isn't going with me this time and I want to stay at PH comped using her as a companion rather than Bally's by myself what will happen if they do ask for her and her card at check in? What are everyone's experiences checking into a CET property using a companion's card number?
