Tough question ! We did a 2 month trip in 2014 and made reservations for every night. Decided it was not needed because every park had empty spaces. Reservations kept us on a schedule that we wished we could have varied a bit. Similar trip in 2017 with no reservations . Had to change route constantly because all parks full !! I would advise make reservations at most popular areas and then wing it. But be prepared. Have a great time. Looking forward to our next western trip in 3 years.
you did this in the summertime and on the West Coast?
