According to Google Maps, approximately 150 miles from Lake Havasu to Las Vegas.
Since you have 2 nights at GC you can see everything on your first two days and then get up a little early and leave for Antelope/Horseshoe. Havasu Falls....I think it it unrealistic to drive 3-4 hours from Vegas to the trailhead parking, then hike 8 miles down to the village and another couple miles to the falls. And then spend one night and hike back out the next day. You're going to want an early start to avoid the heat.
