Las Vegas

I've been to Las Vegas several times[;] it's really a good place to relax.

People [say] there are three things you must do [] there[:] [the] buffet[s], [the] show[s,] and [the] casino[s]. [more a list, so no need for quotes]

I did have the [b]uffet but it [was] just [so-so].  I really love the show[s] and the casino[s].
I'm not a gambler, but it's really interesting to play the slot machine[s].
I saw [] <em>O</em> and <em>KA</em> [] and [] will see the <em>Blue Man [Group]</em> next time.
Other [than these], do you have anything [else you'd] recommend?
