We were there in 2006 - stayed at what was then Landing Zone.
We figured 3 days. When we checked in about noon or so and told them 3 days they wondered what we knew that they did not in regards to CofTM! So we thought we would check it out that afternoon. Basically covered it in a couple hours or so!
We did do a hike and we were treated to the Arco Fourth of July Parade - maybe 12 minutes worth of your usual small town parade. But, being from a small town in IL growing up we truly appreciated it - the baton twirlers / droppers, farm machinery, fire engine, etc.
I think it is worth a stop but would not plan more than a day even with a hike.

We stopped at Craters for a couple of hours two years ago. It was on our way as we were travelling from Jackson, WY across to Boise, ID then on to Columbia River Gorge. it was kind of interesting to see, but I wouldn't recommend spending a whole lot of time there. We stayed at a small campground in West Magic that was nothing special but it was inexpensive and had full hookups. Sun Valley, which is about an hour NW of Craters was nice a sidetrip.

One day should do it. My kids were 12 & 9 at the time and for whatever reason (o.k., my kids are weird.....) they enjoyed it very much. They insisted on a 2nd hike up to the top of Inferno Cone! We have nothing like that here in PA so it was unique and interesting to us.
We stayed at Mountain View. Owners were very nice. The place was clean & quiet (this was in 2004). We had a commanding view of the Number Hill from our site. On our way to CotMNM we had to stop and wait for a real cattle drive to cross the road - that NEVER happens around here!!
I agree with the reply re: the night sky. SPECTACULAR!! CloudDriver - I have pictures nearly identical to yours from Indian Tunnel.
Eat at Pickles in Arco. There was also a farmer's market somewhere in town where we bought fresh fruit & vegetables.
All in all a unique place and worth the time we spent there.
Craters is one of our favorite places. We try to stop whenever we're in the area and will be back again this August/September on our way to Yellowstone. If you don't need hookups, the campground in the monument is quite an experience. Otherwise, I recommend Mountain View.

+10 on the KOA in Arco and EBR-1. The Koa owner told me about a nice private hot spring. If you are adventurous try taking the road over the mountain to Pahsimeroi Valley to Barney Hot Spring (more luke warm) but full of colorful tropical fish. I actually towed my pop-up over the pass and camped near Barney HS. Then the road is good all the way to Ellis. A couple of years ago there was a restaurant out in the middle of nowhere along that road.
