I can't find any information. It seems they are travelling together although they are not offering doubles.

I noticed them too, they're very attractive.  However, I'm saving my money for Olivia next week.

Somebody’s been watching the news…

I’m jealous – I really like Olivia’s style…

Now as to Sexie Lexie and Laisha the related link below is to a profile for “D’Eva Longoria” that shares the common phone# in question – too bad only one review from, you guessed it “SexieLexie”, hmmmmm.   You have deduced that they are traveling together – the descriptions are so close might they be the same person but with two ads (ahh the wonders of modern digital photography)?
