Can locals or epople who have doe it comment on staying in Island park, ID as a base for a couple days seeing Yellowstone? We have 2 nights in the Canyons booked and were thinking of a home in island park for 3 nights also, esp. to see the western half of the park. Is the drive just too long? Ive heard 20 minutes but i ewant to verify with those who have actually done it before we decide. Thanks!!
