Well lots to choose from, I like the added utility of a shuttle. It opens up lots of other possibilities. After reviewing the NPS website, I didn't get the idea there's public shuttles, everything is private?
I've beginning to think we'll have fun wherever and likely will schedule another trip. Lord knows the park is huge and one could spend a lifetime exploring it.
I enjoy the planning piece of trips, but the main backpacking season is waning, maybe one more trip to Moab.
At any rate, great early season snow in Colorado, time to wax the boards.
Thanks for all your help and insights, I surely will have more questions after doing some more research.
