Dont give up on going to Denali. It is a 4-5 hour drive from Anchorage and some of the best moose photography in the world exists at mile markers 8-13. This section of the park is open to private vehicles until you hit the gate at roughly mile 15. Cruise this section of the road, back and forth, until you see a traffic jam. The jam usually indicates moose close by.
I would also take the park bus as it can take you to Sable Pass which is a common area to find bears as well as the occasional wolf.
