Hi Liz
To be honest - you won't get much time to look around on your own anywhere. That's why its important to do the excursions, if you can and your budget allows.
We didn't see anything of Denver because we arrived at the hotel about 8.30 at night and left early the next morning.
There was time to look around Jackson (if you didn't do the Snake River Float). I opted to do this because I wanted to see Jackson and it is a lovely town so I was glad I did that. But the people who did the Snake River Float said it was worth doing, so you have to decide what you prefer to do.
There is some free time in Salt Lake City on the second day. I decided to visit the shopping mall and ride back to the hotel on the free tram.
As I'm sure you're aware, this is a very full-on trip with hardly a minute to yourself. You'll be up early in the morning and sometimes back to the hotel just in time for dinner. Other times you may get a couple of hours spare time when you get back to the hotel. But, believe me it is all worth it. I wouldn't have missed it for the world.
If you haven't read my review yet, it might help (on the review area of the site).
If you need any more help, please don't hesitate to ask
Kind regards, Olive
