Where to stop on drive from Åndalsnes to Drøbak?

My wife and I will be visiting Norway in the second half of August. We have most of our itinerary planned, but are looking for information about one more potential stop.

We are spending the first half of our trip in the west, before visiting friends who live in Drobak. Our final day in the west will be near Andalsnes. It's a six hour drive to Drobak, so are wondering if there was anywhere to stop to break up that drive and spend the night? This is what the google maps route looks like now: https://maps.app.goo.gl/4z7XXqqi2bfSUwYt9

Seems like we could also go a slightly different route than that suggested one and go thru Valdres, which would be right around the halfway point.

Interested in hiking/biking/water activities, would consider a camp spot, but also wouldn't mind a small town. If there's anything that comes to mind, please let me know!
