We did the Grand Canyon for spring break last year. Our itinerary was...
Fly into Las Vegas
One day in Vegas - saw some of the highlights and then drove out to Red Rock Canyon for a short hike
Drive to GC via the Hoover Dam (very impressive)
Stayed 2 nights in GC at the Bright Angel Cabins, right on the rim.
Hiking and some jr. ranger programs in GC and just driving around the rim to see the view
Drove to Flagstaff, stopping to see Meteor Crater
1 night in Flagstaff. Visited the Lowell Observatory in the evening
Drove to Scottsdale - stay 2 nights at the Arizona Grand Resort, which has a big water park
We'd planned to do a Sonoma Jeep Tour but one of the kids got sick so we skipped that and just relaxed at the resort
I don't particularly like Las Vegas but my 12 yr old wanted to see it. He wasn't impressed either but glad he can say he's been there.
