Response:
That's a great road trip! A group of 7 people can fit perfectly on a 7 seat car that you can rent in one of the many providers in Las Vegas. Start your day early in the morning to get the car and pick up your friends. From there your first destination is going to be the Hoover Dam, around 40 minutes by car from Las Vegas. Take your time to take pictures from the bridge and then go the dam, you can visit inside, the self-guided ticket is $10. You will be there for a couple of hours.

After these you need to go south east and take a turn to Dolan Springs, this will be an hour driving, so by that time you are around lunch time, which will cost you approximately $15.
From Dolan Sprints it's a straight 50 minutes ride to the West Grand Canyon. In the road you will find midway the Arizona's Joshua Tree Forest. Take the time to appreciate it, as well as the desert along the way.

When you arrive at the West Grand Canyon, you can buy the $70 general admission ticket + Skywalk. This gives you unlimited access for the day to Eagle Point, Guano Point, Hualapai Ranch and the Skywalk experience. You can walk the sky on the 10-foot wide, horseshoe-shaped glass bridge that extends 70 feet over the rim of the Grand Canyon.

When leaving the West Grand Canyon the trip back to Las Vegas takes 2h. You will need to refill the tank, before returning the vehicle to the car renting company. The renting for the day and the gas will cost around $35 per person.

Depending on your pace, this is a morning and afternoon road trip. With an estimated cost of $130 per person.
