This looks like fun. Might give it a go when we're over. http://m.lasvegassun.com/vegasdeluxe/2016/mar/09/sneak-peek-under-construction-topgolf-las-vegas-/ Opens in May.
I was disappointed when I read this article. I was hoping it would be open when I am out there for a golf trip at the end of April. Oh well, I'll have to check it out next time.
I have been to the Top Golf in west Houston a few times. It is pretty good - I definitely recommend it at least once or twice. I will say that it seems really designed to attract corporate money (expense accounts). In any case, I expect this to do very well in Vegas!
We have it in Phoenix too, ironically with Talking Stick Casino in the background. I agree with what others have said, go with a group. I took a date there, and it was NOT inexpensive. Good times, but you are charged by the hour, rates ($45/hour) go up throughout the day. Go to have fun, not to sharpen your game.
