I visited Las Vegas this summer and it was a pleasant experience. However there were some things that I did not expect to happen.
First, the airfare was considerably high compared to other vacation destinations within the same distance. Another feature of Vegas that I didn't find appealing were the vast amount of people handing me random junk on the strip. It was usually cards and magazines for Las Vegas "escorts", aka hookers. This is a big reason why I believe that Las Vegas is definately more of an adult vacation spot, than a family vacation destination. Also, everyone always talks about how you can get really cheap buffets in Vegas. Well the cheapest one I saw was $15, which is still pretty high.
However there were a lot of good things too. I was there for four days and got about 3-5 hours a sleep a night on average. I got maybe half of the things done that I wanted to do. There is just SOOO much stuff to do in Vegas. I recommend going on the Hoover Dam tour. It is very interesting! Also, the Star Trek Experience at the Hilton was AMAZING! Overall, my Las Vegas experience was fun.
