Are there any celeb sightings in Vegas? Or places where celebs go where you can see them? I know celebs probably don't want to deal with us fans, but I think it'd be fun if they have any meetups for fans.
I have seen a few just walking the strip. They tend to just hang out around luxury spots and private events. It is rare to actually be close enough to talk and interact with them. They usually have a good 5+ body guards with them at all times.
A friend of the family saw an actress once at a dining event. I can't remember the name of her, it was an older actress. But it was hosted as a sort of meet and greet. You buy a table and have the opportunity to say hello to her. This was back in 2011 though.
No matter what time of the year you go, you will almost always see at least one celebrity in Vegas. Be it an actor, singer, sports player, or reality TV star. You are more likely to see the last one that I mentioned though, especially if they are filming nearby.
