Order of travel was switched without notifying us. We were scheduled to ride the train up to Bennet Lake and then bus down on the return. We did not find out about the change until we were told to board the bus. Temperature in van/bus was cold. We repeatedly asked the driver to turn up the heat, but there was no noticeable difference in temperature. Stop time at Bennet Lake was extended from 45 mins to 1 hour without asking if the time extension was agreeable to us. This was especially annoying because mosquitoes were particularly bad at that time, and part of the trail was closed to our exploration due to a bear sighting. We could have used less time, not more time at the site. The RR history itself was interesting and worth seeing. Staff could have been more sensitive to our interests and needs.
