My husband and I plan to travel the last two weeks of June 2014 from SW Okla. We will take 2 days to get to Cody Wy. Day 3, we plan to drive to East Entrance of Yellowstone. Will be have time to see the falls and the lake in this area? It looks like we will have time to drive north thru the park to Mammoth springs and spend the next two nights in Gardiner. Day 4 we plan to take a day long horseback ride (the horseback ride company is near Mammoth) Day 5 -What should we do on day 5? Should we soend another day around the North side of the park or travel to West YS and see the area around Old Faithful. Where should we stay in West YS area? After YS we plan to go to Grand Tetons, and Jackson WY. How many days should we stay in this area? after the Grand Tetons we will travel South to Zion NP. How many days do you recommend stayin in Zion? We will have a two day drive home from Zion to SW Okla. Looking forward to your ideas.
