10K to Half-Marathon in 8 weeks possible? (Beginner runner)

19F, since September, I've been running 2-3x a week with 5K times of around 35 minutes (8.5 km/hr) and can run a 10k at a slower but consistent pace of 7km/hr. I also strength train 2-3x a week.

I'm going to Hawaii in about 2 months and was planning to run the Maui half-marathon (insane scenery), would I be stupid to do the half? If so, I know running longer runs is the first step, but what else should I keep in mind?
