We plan on travelling from Sedona in the morning entering the park from the East Rim Entrance. Driving to the welcome center and doing some hiking around the South Rim from there. We want to see sunset and then also the dark sky to hope to see some stars. Is it possible to leave midday to checkin/rest/eat back to a hotel in Tusayan, then head back into the park for sunset and stay a bit late before heading back to the hotel? Is night time as beautiful as people claims to be?
