Venting - don't really know what to do

So we're eloping in Montana in a week. I've been the sole planner for the last 6 months and I made all the reservations. I booked our lodging in Kalispell, on the west side of Glacier National Park. They closed the entrance to the west side. This means that every time we want to go to Glacier National Park, we will need to drive 1.5-3 hours there, same amount of time back. I totally fucked up the whole trip. I figured we'd be eloping in Kalispell and it's right next to the west entrance, so it'd be the best location. I didn't realize that the west would close before the east, and on the 1st. I thought it'd be later in October. I feel extremely guilty and I don't know what to do. Maybe it's because I'm. Starting soon but I'm honestly freaking out. I need to tell my future husband that because of my stupid mistake at least 4 hours will be wasted every day of our vacation with driving. He's never going to trust me to do anything important again. He already calls me Ditsy (in a nice way, he says it's cute) so this is just going to be on par and he'll think even less of me. God I feel so fucking dumb.

Ps I can't cancel the lodging, it's nonrefundable
