Unfortunately, unless it's mentioned on the news, you don't have much chance of anyone giving that info out on these boards as it's kind of a naughty subject to bring up if you know what I mean.
I can tell you, directly from someone I was speaking too this evening who's very much in the know, that towards the end of their stay at the Versace, they were a little less enthusastic to come out and meet and greet for a number of reasons.
One over enthusiastic fan hurtled up to Larry when he was signing for somebody else and was bluntly told by Larry, and I quote, "Get the fuck away from me" (this fan was apparently very over the top and scary!). I was also told that on Saturday, Bono almost moved to another hotel because the crowds were getting too much.
The other thing is that certain people were standing out there every day getting things signed and a certain couple of band members specifically thought these people were probably not fans but people trying to make money from the band by selling the goods on. By all accounts there is a code the band use when they sign things that their team look for when locating signed good on eBay. Where that gets them I don't know, but apparently a Bono autograph these days without the year included on it, is one of those codes...so if you get one of those, Bono thinks you could be a profit making eBayer!!
Anyway - I got to meet all four band members and they were really cool to me. 22 years of being my favorite band and I finally manged to meet, shake hands, have a few words, get a few pictures and video clips of me with them and get my U2 by U2 book signed (and I got an 06 on my Bono autograph!).
All that by the by, it's not impossible to meet them. If you do find out where they are, it's then about perserverance!! Good luck on your quest guys.
