The facility a 3-4 just because there was plenty to do also the price was a decent price especially through Groupon. Staff for the most part were really helpful & friendly. We went two hours before they closed so it we made sure we tried to do enough with that time which we did. You could do everything in 2 hours & take your time especially if it's a dead day. Take advantage of just doing things more than once if you get the unlimited two hour. The only thing we didn't do was the arcade games but Vegas has plenty of that. The best ones to do are for sure the ninja warrior coarse, zip line, & the boom ball gun game. With lil ones the maze tubes/slides, mini golf, & mini bowling are good. Just make sure to bring water to keep yourself hydrated!
