Do you need an ID to do a short term room rental at CC?

Always have your ID with you. As far as the room.Good question.

If you take a CC chica up to one of their rooms for ariba for 30 minutes you will not need id. If you get stopped on the street by a crooked policia, you will need your id.

You are supposed to have a valid current passport and a Mexican “Tourist Card” (FMM Card) or tourist “visa", in your possession at all times when visiting Tijuana Mexico as a tourist. A tourist visa is a document that authorities use to "Manage Security Concern" in the country being visted by law abiding tourist. If you have nothing to hide and era not a criminal with a record, you should be happy to show your passport and Tourist Card” (FMM Card) when asked for by anyone whit the authority to verify you are a tourist visiting the Happiest Place on earth. [view link] Just be careful out there, as careful as you would be visiting any country red light district.

The only place I have ever used ID south of the border is Hong Kong for the VIP card.

I've enjoyed a number of girls arriba at Chicago over 9 years but hotel jalos is not up to standards. The chicago girl really got to knock my socks off for me to take her arriba at jalos.

It's not clear to me, but it seems there are two hotels linked to CC: (1) Hotel Jalos and (2) Hotel Leyva (possibly named Hotel Posada de Santiago after remodeling). I may have that wrong, but piecing together the limited reviews, it seems like Hotel Jalos is their hotel for short-time engagements, and Hotel Leyva/Posada is a bit nicer and a better choice for booking an overnight room. I'm hoping someone can confirm. I probably won't get down there again this year.

BTW, regarding ID, I agree it is unlikely they will ask for short-time. It used to be you could even book an overnight room without ID, but HK/Cascadas started checking recently. I have also seen others mentioning the FMM tourist card, but in ~10 visits I have never purchased one. I always cross over the pedestrian bridge. The agent on the Mexico side usually takes a quick glance at my passport and waives me through. On two occasions, they asked a few questions and stamped my passport, but never mentioned the card. It could be because I am crossing on foot and only staying for 24 hours.

my experiences, the Mexican agents are inconsistent requiring an FMM.
