Both tours were extremely well organized and pleasant. The only problem I had was that I was never faxed a copy of my reservation. Since I did not have a printer available to print out my voucher, I had to take a chance. Not a pleasant feeling when spending this kind of money and traveling to get there for the tour. Had a local phone number been available this issue could have been solved. Will not use Viator again just because of their lack of cooperation with getting the voucher to me.
