i've learned that very detailed and very kind (even slightly apologetic) emails work best. i don't think ANY clubs/lounges sell day passes anymore. i may be wrong on that. but i think the only day passes that are "out there" are via ebay or cc promotions.
regardless, the point is they are asking something that doesn't correspond with their t&c.
i'm not sure what the email response you got actually means? i would email them back and ask specifically what they mean.
i would advise NOT emailing them every day. i did it. and they told me to be patient and i'd eventually receive personal replies. which i did.
if you call that phone number i posted, call m-f 9-5 if you want to speak to a supervisor. i've done this once and the guy i got kept repeating the same thing over and over and wouldn't directly address the t&c issue.
also, yes, bobby adams was 'da man!
good luck!!
