Denali is a great visit, they say only about 1/3 of all the visitors actually end up getting to see the mountain. I got to see it on the drive up from anchorage, and then again when we took the bus ride to the back, so i've seen the whole mountain.
I went up in 2019 but I did it the fun way. I drove. Hooked up the camper to the truck, and did a 6 week road trip. We hit the arctic ocean in Tuk (Canadia), Valdez, Seward, Homer, Haines, Anchorage, Denali, and Hyder. Best road trip i've done, and my biggest regret was we didn't go north and drive up the haul road. Woulda been nice to drive up and over Atigun pass, spend a day or two enjoying the scenery, and then come back down south.
I definately recommend Valdez, Seward, and Homer. If you're feeling sporty, check out Mcarthy (spelled wrong most likely). Chicken is fun, but you're going to spend a while on a dirt road to get there. When/If you visit Homer, make sure you're hungry, cause everybody has their own fish and chips, and they're all amazing. Charter a boat in Homer, go catch you some sockeye, or halibut, maybe the occasional rock bass. I chartered a boat for 4hrs for my daughters and I, I only pulled in one, and let my girls pull in the rest and we brought 14 on board. We had Salmon for dinner every evening for a week until my girls said they wanted something else.
If I could spend my summers in Alaska every year, i'd do it in a heartbeat.
