Stuck in Leavenworth with a child

We took the Amtrak to Leavenworth from Seattle and we had to take it back home. But the Empire Builder is late by approx 12 hours. A couple of options we’ve explored- 1. There’s a greyhound tomorrow afternoon- is that reliable? 2. Go to Wenatchee and take a rental car. We brought a car seat too so this works. But, how do we get there? We see no Ubers around. 3. Keep waiting for the train and catch it Would appreciate any other recommendations or options to go back home.
