Both drives are similar, lots of miles of 2 lane highway, through deserted desert (if you don’t count the hazardous cows).
If you want to explore the Bullfrog facilities, park at a Bullfrog slip and ask the shuttle to take you to the hotel for a drink or lunch. I can’t say the hotel, gas station and asphalt parking lots are a lot to look at. The high school is a bit of an oddity, but that’s it.
Fun to say you’ve seen it, not sure it’s worth the extra 2 hours. The trip around the North lets you take in the Hite overlook, also fun to say you’ve seen it.
