I agree. A rental may be your best bet. Another thought is not to go across the Rockies. You have plenty to see and do from Alabama to Colorado, north through to Yellowstone then start east. We spent almost two weeks on just Yellowstone and the North Dakota Badlands-T Roosevelt Park. National Parks have wonderful programs for all ages. Your children are only 6 and 10. That is a lot of drive time. Most children (me, too) appreciate 'down' time to play, explore and appreciate the unique area rather than other exhausting amusement park (that can be done on short from home trips). IMOHO
