Having a six year old I can say that I've been to just about every indoor playground / trampoline park in the Valley. That being said , I would say that LOL is probably the best indoor playground in Vegas. This place is massive With a ton of play areas , structures, ball pit and a cool air gun system. This place also has a soft foamy floor throughout the facility (socks only when inside ).
I enjoy that the structure are big enough to where an adult can navigate them without waking up with a sore back the next day. I also like the steepness of the slides and how their structure has four interconnected levels.
The place was very clean when I was here (including the bathrooms). The staff seemed friendly and cordial.
I didn't get a chance to try the food but they seem to have an extensive menu with dedicated "chefs/cooks". They also have a ton of desserts.
The price point is probably the highest of any playground in Vegas at $16.xx for myself and my kid but considering the amount of she had , I'm okay with the price.
PROs: MASSIVE, foamy floor , multi level play structure , multiple slides with nice inclines for a fun ride , clean , not too busy
Overall I think this place provides a good value when measuring the amount of fun your kid will have and the price you pay. Will come back every few weeks.
