Just to help...
Week 27 is usually Fourth of July week so that's kind of fun

Other things going on during that week include: world series of poker,
Cliffs at Peace Canyon is located in Summerlin which is the west part of the Vegas valley. It's near Red Rock Canyon, Red Rock casino/hotel, Downtown Summerlin (shopping area with movies and events), City National Arena (the new ice rink that the Golden Knights practice at) and coming soon there will be the Las Vegas Ball Park where the 51s will play.
Cliffs is more like a condo complex than a resort. So that makes it very neighborhood-y and family-friendly. When you go you'd probably want to rent a car since it's a drive from The Strip and most tourists want to spend quite a bit of time down at The STrip.
