Is there anything else you would like to add?
Given that this is the first time Exodus have run this trip I'm hoping that they will be open to making a few changes before 2012. I would question why the trip needs to return to Salt Lake prior to flying back to the UK - as that is 2 days of solid driving. I think it would be better to use one of the small airports closer to Glacier NP. This may result in 1 extra airport transfer, but I think all the group plus the leaders thought it would be better than the lengthy drive at the end.
This is a really special trip to some amazing parks. It can only be run over a short period due to the weather, so if you want to hike with bears, wolves and bison then get signing up for next year!!
