I've actually been to Las Vegas (where MGM Grand is.. from Candy's post) and I didn't like it very much. There were plenty of people, but I had the sense I was staying in the wrong part of town. I should not have booked that budget room...
I live near it, and I never go. I have a decidedly pessimistic attitude about swimming in the ocean. But it is awe inspiring, and very nostalgic. When I was young, it was really fun to go to the beach!
I didn't really go to get in the ocean... Although I would... But I like to go to the beach to people watch lol And at night when everyone else goes in their hotels.... You never know what you may see lol
