it's a fun experience, however...
it's expensive.
secondly, they do not tell you that you cannot bring a phone or camera inside until you've already paid to get in. They tell you photos are available for purchase or you can share them on facebook or twitter. that is a big fat lie! When you share the pictures on fb or twitter, there's a huge "DO NOT COPY" watermark on it, so essentially, the only way you can get the picture is to buy a copy for $20.
i know i know, it's vegas, everything is expensive. but after spending about $30 for the entry fee & one cocktail, i do not care to spend another $20 on a picture.
i'm most annoyed that this was not clear to us.
