The OP has a legitimate question. What type of i.d. is asked for if booking a corporate rate? It's not the first time the question has been asked on this forum, nor will it be the last.
From the responses (some of which are more polite than others), the OP now knows the type he'll need or that he might be asked to pay rack rate. He's also been told that Priceline is an option to reduce hotel costs & which forum might give him additional information on how to book Priceline. I think he would have more success with that than trying a LNF scenario.
His personal life is not our concern other than it helps us to understand why he's looking for a less expensive rate & why he doesn't want to stay in a bad section of town. I would hope that my fellow FTers would respond with information that's helpful or, if they feel they don't have information that would be helpful or can't post without being snarky, that they'd just refrain from posting & move to a different thread where they can provide help information in a friendly fashion.
Cheers.
