Hello & thank you in advance for your help. Visiting from NZ for Xmas time. We have 15 days from date of arrival into LAX (Dec 22). Could you please suggest an itinerary for the above destinations, spread over the 15 days, with return to LA ... and especially with somewhere special to spend Xmas. We don’t mind passing through Vegas but have little interest in staying there for more than a night. Active family, two older teens, love hiking and adventure. Visited Zion and Bryce when children were a lot younger 13 years ago. Many thanks!
