Thanks everyone for the suggestions. I think we are going to DIY, rent a car in Anchorage, drive straight to Seward. Stay there for 2 nights, thinking between VRBO or lodge/hotel, doing a Kenai tour and maybe glacier hike, maybe send the DH and kids fishing. Then the last day we'll head back up to Anchorage, take the day to explore the area and drive North and then fly out the following day. Thank you to everyone for your suggestions. I had really thought about Denali, but sounds like between the distance to get there, road being washed out and other factors, we'll stick to Kenai peninsula.
