We are planning to visit GCNP in two weeks - 4 nights in mid-June. We are considering reducing that to 3 nights and spending the 4th (or 1st) night in Sedona. Never been to any of these places. Is overnight visit to Sedona adequate to get a glimpse so we can decide if we need to come back and spend a week there in future? We are a family of 4 with two teenage daughters. What can we don from noon to noon - 24 hours? Thanks in advance for any suggestions.
