Ive taking a number tours over my 52 years and this was by far the worst ive been through. Tour guide Brandon acted in a very unpleasant and unprofessionally. Apparently the phrase "good to go" is a slur and Brandon took offense using such term and went off in a unhinged rant before the tour started. This rant put the tour in a downward spiral. Yep nothing like spending a $1000 for a tour (5 of us) only to get yelled out for saying " good to go". Fun times, Not!!
