Glacier would be difficult in a tear. Only so many boats are allowed in each day.
However, Denali would easily work for a tear. With exception of once a year, personal vehicles a restricted from more than 10-12 miles into the park. Only approved tour buses is they way in. You can take a day trip all the way into the camp just past Wonder Lake and back out again. It is like 12 hours, but well worth it. Outside the park are tons of camping, cabins, etc.
If you get to Alaska, Denali should be on the list. Another fun place is Chena Hot Springs (with the Ice Hotel) -- I don't remember if they have formal camping options there or not.
