Great experience. Staff extremely nice and professional. As many people have stated the ride is weight based however you can request the front seat(not a guarantee tho). Two small pieces of advice for better experience, don't wear bright clothing because if you are next to window, it will cast a reflection on your pictures. Also, my wife says leave the ear rings off for the ride, she rode about half the trip with ear rings in and once she took them off, said the head piece felt much better.
Overall a wonderful experience and would highly recommend!
