Review for Grand Sierra Resort and Casino (GSR) Review For Crystal Bar Google User Sep 19 '18 at 6:38 Have never stayed here, but we love the Fun center and visit often. They change up the arrangement just enough to keep it fresh and have added a lot of new games recently. My kids beg to go play there. And an amazing bonus is the tumble town in the center you have to pay a separate price but there is a lot to do so it is worth it. Adults can not go into the play structure so it is not the best for really young kids, but a great indoor area for the kids to wear themselves out. And with all the other restaurants on the same floor you don't even have to leave to get lunch. View full site to comment or like
