We are visiting the area in early July - going to Mesa Verde, Grand Canyon and 2 days in Phoenix (traveling in and out of Sky Harbor). Thought about a hot air balloon trip as we have a 16 year old teen and it could be "cool". Is it??? And is there a specific company or location you recommend over others? Do they only leave at dawn due to the heat? How do they handle cancellations due to weather? THANK YOU!
