I am going to Las vegas in November to celebrate my silver wedding anniversary, and am intending to go on a helicopter trip to The Grand canyon. Can anyone help by advising me which is the best one to do - not necessarily the cheapest - but best value for money for a half day trip. I cannot do much walking as I am a wheelchair user. Also is it better to book it online from UK or book it when in Las Vegas? I would also like to book a strech limo from the airport to the Luxor - can anyone tell me which is the best company (there will be 4 adults) Thank you in advance for any assistance.
