Where are you going???? Unfortunately some land tours have little unplanned time. Best you can do however is to check and make sure you have the "tundra wildlife" tour included to Denali Park and not the useless "natural history" big difference between the 2 little if any wildlife on the natural history and only 17 miles into the park vs 53 on the tundra wildlife. Do get it changed for far greater wildlife viewing if interested. Also plan on the free sled dog demo offered 3 time/ day?? Very interesting and free. Also some great ranger activities. If in Talkeetna definately take a summit flight since this will probably be your only opportunity to see McKinley. Myself, I will never take another cruisetour.
