Here's our tentative plan for September 2014:
We'll have two weeks.
Fly in to Las Vegas, pick up rental car
Drive to Sedona via Oatman, Kingman, (Old Route 66) Seligman Route 66 & I-40 (About what time would we have to leave the airport to make some stops and arrive in Sedona before sunset? Maybe spend the night in LV and leave early the next day?)
Sedona for 6 nights--confirmed res
Drive to GCNP via Sunset Crater, Wupatki NM, Cameron, Desert View Drive
One night Bright Angel Rim Cabin (confirmed res.)
Hike South Kaibab to Phantom Ranch (confirmed res)
Hike out Bright Angel-- one night at El Tovar (confirmed res)
Drive to Page ...River Discovery at 1PM;-- one night Lake Powell Motel
Horseshoe Bend (early), Upper Antelope Canyon(mid-morning), drive to North Rim --one night Grand Canyon Lodge (confirmed res)
Drive to Las Vegas for a couple of nights (mainly to rest.. lol) and fly home --It's tempting to stop by Bryce and/or Zion, but I think they will have to wait until another time.
Thank you for any input, and thanks for all the useful information you have already given!
