The LINQ has come a long way since it's days as The Imperial Palace and the oddly named "Quad' The location is good and my room was clean but I twice has issues with the HOT water in the shower taking several minutes to heat up even then it was only lukewarm.
Check in process rather slow as well - though I've experienced worse over the years.
Biggest pro for me was that they did appear to admit any one under 18 into the pool area. This is fantastic as I hate your kids almost much as I hate you for bringing the vegas in the 1st place. Seriously - stop doing this, and it you must at least have the decency to stay at Circus Circus away from the rest of us.
